Related work-in-progress if you like polyhedra and tiling transformations: https://ixxyxr.github.io/polyhydra-web/

It has the Kepler-Poinsot polyhedra and allows you to apply a superset of Conway Operators to them. No true stellation currently (stellation isn't an edge-replacement operator so can't be mimicked by Conway-esque operations)
