This site has some interesting multimedia stuff, but it varies more towards the professional recognition side as opposed to a tutorial-based site. It's called Cartoon Brew, and it features artists of the day, some of which create their art by computer and make gifs. Some different stuff, but really nice. 

     They focus on animation, like the new film The Croods, and the artists and developers behind it. They really showcase the developers, which doesn't happen often.

This is all about looking into various forms of media..multimedia.. that incorporate various different techniques and styles, some even including GIFs that take the art to another level.

Inspired art.
