My favorite feed in Democracy (soon to be Miro) is http://del.icio.us/popular/system:media:video, or the most popular video files on del.icio.us. There’s tons of good stuff including tech talks, NASA videos, and the occasional amazing animation. For example, take a look at Curare from Swedish motion graphics studio Pistachios, wherein a poker playing thug finds himself on the wrong end of a blow dart.
