Archimedes rides again.

Well, Achimenes actually: I just christened it "Archie Medes".
We used to have "one" for quite a few years some time ago. I/we'd never seen any except the "usual" kinda purplish, single variety. It wasn't until we saw this that we found out there was more than one colour/variety, and only "tonight" I got a hint of the full extent of them.
I don't know about the rest of "Blipmanity" but I'm also rather attracted to reflections & refractions - see "Extra".
