Yesterday I posted about a brilliant xkcd web comic. Today I was lurking around the Internet and accidentally found this entry from Chris Robertson which contains a video homage to xkcd number 442, which itself is a homage to a Discovery Channel commercial "I Love The World". (whew!)
Noam Raby animates a song by Olga Nunes with images and lyrics from an XKCD strip by Randall Munroe, and the result is awesomeness.
This is so meta I can hardly stand it. (huge grin)
