It's a bit Arty. It's not cheap. But for kewl, it's kinda hard to beat Empiric's Magic Lantern Slide Boxes, featuring nature and astronomy themes. (Top row center: oh, yeah!)
Magic lantern slides are around 3" by 4", unlike the later slides you might just barely remember having to sit through showings of at Uncle Oddie's. Large enough to make for nifty backlit viewing!
(Found following up the maker's name from online quirky-decorator site One King's Lane -- requires log-in, they are something of a spot discounter).
