Proposals for a large suspended custom sculpture (mobile) for an atrium at a children’s hospital. The color combinations are based on the interior colors as well as the colors within the logo of the children’s hospital. The overall design concept for the building is derived from nature to include water, forest and sky, blending the exterior and interior experience together, which is also reflected in several of these design proposals.

In 2013, I collaborated with Henry Segerman to create a first of its kind collection of 3D Printed Mobiles. Outside of being Assistant Professor in the Department of Mathematics at Oklahoma State University, Henry has since established himself as one of the leading figures in the new world of math and 3D printing. This month he has a new book out titled Visualizing Mathematics with 3D Printing in which he takes readers on a fascinating tour of two-, three-, and four-dimensional mathematics, exploring Euclidean and non-Euclidean geometries, symmetry, knots, tilings, and soap films.
The book includes more than 100 color photographs of 3D printed models, and has a sister website that features virtual three-dimensional versions of the models for readers to explore.
Read the review on Wired “Can’t Imagine Shapes in 4 Dimensions? Just Print Them Out” and also take a look at Henry’s amazing 3D Printed Mathematical Art.
A custom designed mobile for a private residence in Montana in progress:
For an element (shape) to be able to balance, the suspension point needs to be above the center of mass. In addition to this requirement, when the center of mass is lower (farther away from the suspension point), the balance will be more stable. Vice versa, when the center of mass is higher (closer to the suspension point), the balance will be more fragile (the element is more likely to overturn):
Obviously within a mobile, an element might have the weight of several elements that are in the lower part of the mobile attached to it, which lowers the center of of mass. A good example of this can be seen in a large site-specific mobile I was working on for a three story light shaft in Chicago last year:
In some cases, it might be necessary to raise the suspension point with the help of an extension:
