A story about this appeared in last Sunday's Herald-Times:

You can read more about the public art project in general, and about Matthias' and Jiangmei's proposal "Orix" in particular, here:

At that link, you will find in the upper-right-hand corner a button giving the opportunity to provide feedback.
Quoting from that page, "The generative seed of Orix is a triply periodic bi-foldable mathematical surface that is the result of a collaboration between IUB mathematician Matthias Weber and artist/designer Jiangmei Wu. The DNA of the surface is an ‘X’ shaped vertex that can be aggregated in three-dimensional space. Through a process of adding, subtracting, folding, and distorting, Orix can be generated and optimized into various potential solutions based on artistic compositions, engineering analyses, and community engagement."
