Very cool Nan! I really like the page you added, ‘Wacky things to see’,
with the spoilers of what can happen. I have a Rubik’s Cube at home I keep
with a single twirled corner (I don’t know why, it just makes me smile), so
it’s nice to know I could actually solve it if it were a RefleCube :D

I thought I’d mention that David Vanderschel’s Magic Cube
3D<http://david-v.home.texas.net/MC3D/> program
supports these reflection moves as well. David introduced his program and
mentioned reflection twists in the following post:

It may be one of the topics that provided your inspiration, but this long
thread also has discussion about reflection twists, in various places:

Cheers,
