Not related to the existing program. It's rather a crazy idea, I'd like to bounce. I was always jelaouse of musician being able to play together. Artist's, however, never had that luxury. It's a solitary endeavor.
What I'm talking about is not another childish play like Aggie.io or multidraw.com. There in no need to interrupt each other in real time. There is no need to allow anybody to destroy your stuff. This is how I imagine it:
1. Participating on the project are only the artists, who agree to work together. Preferably but not necessarily, they have to share skill level and type of art, styles, etc.
2. Each works on a separate layer. Each contribution doesn't destroy other people stuff. If you don't like what your colleague did, simply paint it over. You can simply then offer everybody else to turn layers off a day see the changes. If you want, you can "unlock" your layer to others.
3. The theme or idea can be stated in advance or it's a complete impromptu.
4. Network program has to be as powerful as ASP. There is no difference between desktop or mobile. Ideally, it has to be a networked version of the ASP. Or, better yet, the ASP with the network collaboration on or off.
5. Important! No need for the real time update or any of such burden. Everybody can take his/her time and post only when ready.
6. There has to be a sort of quick chat window attached to it.
Let me know your thoughts. I think this can be a total blast, which would make people more creative and you... richer.
