I think whoever posted this needs to step in and explain what's interesting or new or relevant about it, 16 years after the instrument had its first light?

I found Mimir interesting because its design is "near" completely open-source (except AutoCAD files of mechanical designs).[0]

Actually I'm testing Astree[1] app (FLOSS alternative to Zemax) using files & docs of Mimir's optical designs[2].
