A structural biology viewer/editor/CAD-style application. Combines functionality similar to PyMol, Coot, VMD, and GROMACs. Open-source, standalone executable. Built in Rust and CUDA.

And the host of bio libs required to do it. The sort of thing that are mature in Python, for example, but I needed to build for Rust.
