Dang, that's freakin awesome!
When's this stuff comin as a challenge? I would definitly enter that!
Downloading the updated image, tweaking my part, sending it in. Gosh, that would be awesome! Could be like, as you enter with your contribution it is automatically added and every row is like 5 contributions wide before dropping down to make a long thin image... *wanders of a bit, finds lost, got lost, lost lost... 'Mm, Reality', snaps out*... oh yeah by the way!
Nice freaking picture so far guys! Not only do you manage to do something complex and beautiful while retaining the style, you also manage to shift in and out to get a nice mix of styles that's your own! Excellent work guys
