I hadn't thought about kaleidoscopes in years! I liked them quite a bit as a kid. Theoretically they're interesting in terms of the whole like, indefinite repetitions-with-a-difference of a single image. In AQ the word = 223, for 4::3, the lemur of highest pitch and also of perhaps the strangest path (41872563). I think it would be interesting to have some sort of kaleidoscopic ritual there, but I don't know what it would be. I'm sure kaleidoscopes do have artistic value and it'd probably be interesting to use the same kaleidoscope in different circumstances---different weather, different settings, different times of year---and record one's experience. Which is making me wish I had a kaleidoscope to do this with. And they do seem like they'd be a ton of fun to design, and not enormously difficult either! Cool thing to think about.
