There are a number of molecular visualisation tools available (many are now showing their age), but this looks an interesting addition
A modern, legacy-free molecular visualizer modeled after VMD, written in pure Rust. The molecule is drawn with hand-written GPU ray-cast impostors (WGSL) and real-time cartoon ribbons — no OpenGL fixed pipeline, no X11, no C/C++/Tcl. It runs natively on Linux, Windows, macOS and compiles to
WebAssembly
