by the fans for the fans

Does anyone know of any good sites for online artistic collaboration? I was surfing around, and found one:

dreamzone.com/

People can jointly collaborate on a single piece of artwork, to build it up. I was thinking that it might be nice to do a Robotech art project this way, by having multiple fans contribute to make it look as nice as possible. What do you all think?

Wait, after some more surfing, I found another site to collaboratively make simple Flash-style vector animations:

www.doink.com/

Looks cute - I bet this could be cool for a Robotech animation project, too. Any takers?

Here's a list of sites for online audio sharing and possibly editing:

www.shambles.net/pages/school/music/

One of those is a site for online audio editing, and I think it even supports collaborative features:

aviary.com/tools/myna

here's something for collaborative storywriting, although I'm not sure how it works:

www.splitstory.com/

Here is a site for collaborative video editing:

stroome.com/

So again, you can have multiple people jointly working on making and editing a video. Looks pretty fun.

Here's another site I found - it has a feature called Drawchat, which allows multiple people to collaborate on the same drawing while also chatting together in a chat window:
