I recently made a custom mobile sculpture for the TV show And Just Like That … and installed on the set in a loft in New York City last week. Filming took place a couple of days after, and the art department informed me afterwards that the mobile “looked incredible on our set” and that it “was much admired”. The mobile should be visible in Season 2 Episode 5, which will be released on Thursday, July 13, 2023.

This is a photo of the yet-to-be-painted mobile in my work shop:

Made of aluminum, the mobile weighs only about 5 pounds (2.25 kg), so it moves even with the slightest air currents. The dimensions are approximately 10 feet (300 cm) in height and 10 feet in diameter.

Update – July 13th 2023:

Here are screen captures from the episode where the mobile is featured when Sarah Jessica Parker‘s character (Carrie Bradshaw) visits Peter Hermann‘s character’s (George) place.

Mentions of the mobile, although (possibly) mistaken for a piece by Alexander Calder:

Upon request, the design is based on a mobile that I custom-made for a private residence in Long Island, New York about 10 years ago:

Update:

There will be two more mobiles sculptures that I’ve made in Season 3 of the series, of which the first episode was released on May 29th 2025.

The sculpture consists of two parts that visually correspond with each other and complete each other. Each part measures 25 feet (8 meters) in height and 16 feet (5 meters) in diameter. Made of aluminum to keep the sculpture lightweight and therefor susceptible to air movements within the space, the lower part weighs only 47 pounds (22 kg), the upper part only 39 pounds (18 kg).

The custom design of the two-part mobile sculpture, an application of a new approach to expanding Alexander Calder’s art form of mobiles:

The atrium:

Several weeks were spent on experimenting with fabrication techniques and inventing custom tools. Several jigs to facilitate the assembly process were also made. The balance point of each of the almost 50 parts had to be calculated precisely within the 3d model. The balance point of each part is dependent on the weight of the other parts. Each part had to be fabricated according to the 3d model, with some parts needing many adjustments until they positioned themselves correctly. In the process, the sculpture had to be raised and lowered hundreds of times, making additional adjustments to the parts each time.

The sculpture is made with a conventional hook-and-loop structure, as in a Calder mobile. A custom-made bending tool bolted to a table weighing 2 tons was utilized to allow for the metal rounds as thick as 3/4 inch (2 cm) to be bent into tight loops with an inner diameter of only 1 inch (2.5 cm):

Calculated measurement marks lining up perfectly after a loop was bent, ensuring that the balance point will be precisely in the correct place:

The spreadsheet for one of the two sections, comparing the weight of the parts in the 3D-model to the actual weight of the parts as they were being made. The difference throughout the fabrication process had to be kept to a minimum to ensure that each part of the almost 50 parts, and the sculpture as a whole, would balance correctly. In the end, the weight difference between the model and reality was only 0.05% (0.31 ounces / 8.73 grams) of the total weight of the section:

George Rickey, while outlining the early explorations by artists into kinetic art from 1912 to 1932 in his book Constructivism – Origins and Evolution (published in 1967, and to my knowledge, the most wide-ranging and comprehensive book on the subject of Constructivism to date), remarked: “It was Calder who succeeded in securing a place for kinetic art. He started making mobiles twelve years after Gabo’s Manifesto, and his first exhibition of these was in 1932 at the Galérie Maeght in Paris. Although his mobiles have since become famous and popular and have enlarged the limits of art, his style, deriving from painterly concepts, has had little influence on the new generation, especially the more mechanically inclined. Until his stabiles of the last decade, Calder retained a two-dimensional outlook in sculpture devised as outline drawings, often witty, with ingratiating movement added. He seemed indifferent to the wide possibilities of a kinetic art. He discovered a new world but did not explore it.“

To put the idea in different words: Calder’s process began with seeing Piet Mondrian‘s paintings and feeling the impulse to make the static abstract shapes in the paintings move. He translated this idea to his mobiles quite precisely, essentially creating two-dimensional abstract paintings made of a series of flat shapes that move. Most of them only happen to become three-dimensional because these two-dimensional abstract “paintings” (essentially two-dimensional planes made of a series of flat shapes) happen to curve three-dimensionally when moved by air currents. He remained devoted to this approach with his mobiles and veered from it only very rarely, and not far when he did.

In 1962, in a review in Arts Magazine of an exhibit of Calder’s work at Tate [PDF], George Rickey wrote: “The mobile, even if flexible, is two-dimensional, like a drawing on a rubber sheet. The sinuous tracery of each set of wires profiles may sit contrapuntally against the next, but flat against flat. With the parts swinging around a vertical axis, the galaxy occupies space but does not energize it. Calder has run through the permutations of these wire profiles; yet, apart from some perfecting of wire technology, extension and refinement of his vocabulary of shapes (the Arpesque flame forms are the best), and increased size, he shows very little advance in the expressive use of movement in the thirty years since Calderberry Bush [also known as Object with Red Discs, made in 1932 and regarded as Calder’s first mobile sculpture]. It is not the first time that an artist has been confined by his own invention; it happened to Samuel F. B. Morse. The Master of the Catenaries has become the prisoner of the chain he forged.“

To expand Calder’s idea, one could create mobiles with the same balance structure as Calder’s mobiles (based on the whippletree mechanism), and create moving abstract “paintings” that are truly three-dimensional, not just two-dimensional planes made of a series of flat shapes that curve with the air currents.

In his later years, Calder designed and made some of his mobiles consisting of two (or more) horizontal and vertical planes, each one being essentially arranged in two dimensions. His hanging mobile titled Lone Red Among Blacks (1961) is a good example to illustrate this. Here again, the three-dimensionality was a result of combining two or more “flat” two-dimensional arrangements, not of a fully three-dimensional arrangement.

These mobiles shown here are still designed with the interconnected balance structure where the balance of each part depends on the other parts, as in a Calder mobile. And same as in Calder’s mobiles, it’s essentially an upside down whippletree mechanism, which probably dates back to between 190 to 209 AD, and has been used to distribute force evenly through linkages when horses or mules pull a plow or a wagon:

Man Ray was the first artist (to my knowledge) to utilize this balance structure in a suspended sculpture with his piece titled Obstruction in 1920 (if you’d like to read more about the history of mobiles, please see my page Mobiles before Calder – Who Invented Mobiles – A History of Mobiles Part 1).

Almost all artists who have made mobiles since Calder have adapted his two-dimensional approach. Few have worked to move beyond and explore the possibilities of fully three-dimensionally designed mobiles that utilize the interconnected balance structure that distinguishes them from simply suspended sculptures (please see my page Mobile Sculpture Artists – A History of Mobiles – Part 2 for some examples). George Rickey recognized the limitations of Calder’s two-dimensional approach to mobiles and expanded the art form, although many of his pieces don’t utilize an interconnected balance structure throughout. After around 1950, he often also opted for standing sculptures instead of suspended ones. Lynn Chadwick, Tim Prentice, Jerome Kirk, Derick Pobell, Laurent Martin “Lo”, Philippe Jestin and Jade Oakley have found ways to some extend to free the art form of mobiles from Calder’s two-dimensional approach. Tim Prentice expressed the challenge in a conversation with Nicholas Fox Weber (published by Maxwell Davidson Gallery in 2000): “Calder was credited with inventing sculpture with moving parts, so for me Rickey was incredibly important because he demonstrated that this concept wasn’t any one man’s property. I can do it to a limited degree. I can draw a line and have it curve, undulate, curl, turn, twist – in that sense, the line is changing – and I can do it with planes. The next challenge would be to do it with volume.” Volume as in three-dimensional planes instead of two-dimensional planes? Or no planes at all?

On the topic of Calder and Rickey, Tim Prentice wrote in his book Drawing on the Air – The Kinetic Sculptures of Tim Prentice: “If you compare the two, Calder was a great storyteller [and an entertainer] and not a theorist. When anyone asked him tough questions about his work, he hid behind his humor. For example, when asked how he knew a piece was finished, he famously answered, “When it’s dinner time.” He operated entirely on intuition. By contrast, Rickey was an intellectual and teacher. He was far more strict in his use of Constructivist principles. He analytically isolated movement in the way Josef Albers isolated color. [Rickey] and Calder represent the two contrasting sides of the brain.” Tim Prentice’s work greatly expands the art form of mobiles. He seems to build on Rickey’s approach more than on Calder’s. As he himself has explained: “As I concentrated on reducing weight and friction, the decisions came to be based more on engineering and less on aesthetics” and “we make the machine and keep our artistic instincts out of it and the air comes along and does the art.” Can the contrasting approaches be combined in new ways?

Building on Calder’s hanging mobile 13 Spines (1940):

Photos reverse the idea of turning an abstract painting or drawing into a three-dimensional moving sculpture. They turn it back into a flat immobile image made of abstract shapes. Two-dimensional layouts in mobiles, like many of Calder’s mobiles and the more conventional mobile sculptures I made some years ago, are easier to capture and comprehend in photos. While video can provide a solution to this, most people discover new art in the form of photos nowadays, especially now in the digital age. You can make an amazing three-dimensional sculpture, but if the sculpture doesn’t allow you to represent its idea comprehensively in images and photos, then you’re limiting the reach of the idea greatly. As Sarah Sze put it in an interview with Melissa Chiu: “In many ways, great artworks are known primarily through photos – so arguably the photos are as important as the artworks themselves.”

An approach that seems architectural to me:

The balance structure of a mobile (the whippletree mechanism) is like a few simple chords on an instrument: simple, but the possibilities of what can be done with it are infinite.

“Paintings are but research and experiment. I never do a painting as a work of art. All of them are researches.” – Pablo Picasso, in an interview with Alexander Liberman for Vogue in 1956.

Or as architect Santiago Calatrava has pointed out: the surrealist André Breton said, “Everyone knows what a head looks like”, to which Alberto Giacometti retorted: “Not me.”

See the continuation of this post Contemporary Mobile Sculptures – Expanding Calder’s Art Form – Part 2 with additional new mobile sculptures that I’m working on based on this approach.

Made out of aluminum and stainless steel and with a diameter of 60 inches / 150 cm, it weighs less than a pound / less than half a kilogram, and therefor moves with the slightest air currents.

Unlike a conventional mobile by Alexander Calder, this is essentially one mobile made of three mobiles. I believe this is quite unique and original, I’ve not seen a mobile like it.

Marco Mahler gives new life to the kinetic art form Calder made famous

It talks about how I got inspired by Alexander Calder’s mobiles at the National Gallery of Art’s Tower 2 in Washington, D.C. to make my first mobiles, then made small mobiles and kinetic sculptures that I sold on online, got commissioned for a series of mobiles for a New York Fashion Week, winning third prize in the 2015 International Kinetic Art Organization competition, a custom mobile for Robert A. M. Stern, New York architect and dean of architecture at Yale, collaborated with mathematician Henry Segerman to create 3D printed mobiles, a custom designed mobile sculpture that I made for the 2019 movie The Upside starring Bryan Cranston and Nicole Kidman, and some of my new ideas for suspended kinetic sculptures for future projects.

Mobiles shown in the article are Mobile 92 and one of my original contemporary mobile sculptures. Some of the 3d printed mobiles and a shape for a large custom mobile are visible in the background, as well as some of my other contemporary mobiles.

Thanks to Elizabeth Cogar and R•Home managing editor Susan Morgan!

Incidentally, a mobile that I custom-made for architect and former Dean of the Yale School of Architecture Robert A.M. Stern for his room at The Kips Bay Designer Show House is featured in the following issue of R•Home Magazine in the feature article about interior designer Doug Stiles and his condo in Richmond’s Bellevue Square where the mobile is currently suspended:

These are true mobiles, meaning they are kinetic and based on the same balance structure as a Calder mobile, yet original and contemporary in design.

I competed against 22 sculptors for the commission including Zaha Hadid.

– See the design proposals that I submitted –

The sculpture measures 33ft (10m) in height and 26ft (8m) in diameter.

The largest shape is 5 2/3 ft long (1 3/4 m), the longest arm measures 17 3/4 ft (5 1/2 m) in length.

Made of aluminum, the mobiles weighs only about 100 pounds (45kg).

From the jury:
“This work highlights the formal possibilities of 3D printing, as the way the joints are combined within
one form is possible only in that new media technique; and despite the hard-edge material, the
movement and lightness of color, with the play of shadow on the wall, creates a sense of dynamic
lightness.”

The above is a render.

Announcements are at 3Druck and PPS.

1st Prize went to Markéta Schiffnederová for her 3d printed sculpture Crumpled Rabbit:

From the jury:
“As a 3-dimensional form, this work is visually interesting from all angles; its subject – an organic
creature – visually has the throw-away quality of crumpled paper, yet the synthetic colour and actual
texture are contradictions to the known sight and touch of both rabbit and paper; and because it
successfully embraces the nature of the medium of 3D printing.”

2nd Prize went to Marc Reist, 3rd to Jean-François Réveillard, and 4th to Oliver Ende.
