Check out Best of Wikipedia (why is all the good stuff on Tumblr? Maybe I should be on Tumblr? Would this site be better and cooler if it was on Tumblr?). It is what it sounds like, and it updates regularly with fun/interesting/kooky stuff. I like the one linked below, highlighting differences in languages’ interpretations of colour gradations (although it says a weird thing: “Also, some languages treat light (often greenish) blue and dark blue as separate colors, rather than different variations of blue, while English does not.” Wouldn’t that be turquoise in English?).

Distinguishing blue from green in language – Wikipedia, the free encyclopedia.
