Andrey Kuznetsov makes delightful lubki (sing. lubok), a form of Russian folk art, out of some well-known modern movies. Some information (in English) about the medium and its origins with many examples can be seen here (warning: Java). Shamelessly ganked from AskMe. Thanks jonson!
It takes a long time to load, but Kol-Belov's "PU's_tota" is just so creepy and bizarre and awesome with really cool music. The artist is obviously deeply weird, also highlighted in the series of shorts, "Self-Destructing Organisms." There's also a game. These are Flash animations. Nearly all of them contain a modest amount of cartoon violence/gore; may not be safe for work. Also, the guy really loves his industrial music.
