Omnisio is a cool site/service – it allows you to create your own compilations of video clips (from YouTube and other such video sharing sites). My current favorite compilation shows the new Weezer video “Pork and Beans”, followed by all of the viral videos that it references – just in case you missed any. Oh, and you can also use Omnisio to sync up the slides from a presentation with (e.g.) actual footage of the presentation.

Second, and in a similar vein, Last.fm + YouTube is awesome. Give it a Last.fm user or artist, and it’ll start playing YouTube videos “related” to the resulting Last.fm stream – music videos, interviews, and the like. If you give it your own Last.fm username, you seasoned scrobblers can get your very own custom music video channel.

When you’re done with music videos, try cartooning. I love watching Peter Shin demonstrating how to draw Stewie Griffin. It looks ridiculously simple when he does it, but my attempts always come out looking pretty lumpy…
