Kaleidoscopes don’t really have a purpose. Made out of a series of reflected surfaces, all tilted at a certain angle so that they repeat symmetrical patterns, they’re mostly used as toys. What they do do, however, is make beautifully weird, sparkly illusions. Which makes them pretty bloomin’ cool.

It’s called LEAPscape, and makes for one wildly trippy experience. Just take a look these pics:s
