I like the idea of this as well! It's definitely understandable if this never becomes a part of the forums though.
Maybe there could be a thread that could be a place for suggestions, and for the collaboration of sonic artists and visual artists... and not just artwork but maybe even videos/effects.
I design for a producer who's been on the road lately and he VJ'd for the first time last night - triggered video clips thru Ableton on a 2nd laptop. I'd like to think that's something that's going to become more common in the future! I'd be down to dive into a forum section like that and collaborate with people here...but that's just me.
