Totally stalking you and Comic's conversation. I saw a good idea for a worm on another site. Basically the dimensions for the piece are like height 300px and width 500px or so.
If you go bigger, there are a lot of people who are inexperienced with LPs and might he hesitant to join because of the large canvas, and if you go smaller, people who do more big stuff may not join.
So 500x300 is fairly big, but still technically tag size.
Just an idea, might help get more people involved in the worm instead of you, Comic and myself. :P
that actually sounds like an awesome idea, 3 man worm where we all make like 6 pieces each
