I did see this thread before, but didn't pay much atention to it. Then, it was posted at the blog
and i thought "well, possibly i should check it out". I'm glad i did!
This is incredibly well done. The concept is so imovative, having a giant wall of drawing is fantastic. Being able to browse through it is cool, and one can see it's very well done (you can't draw all you like, you have a limit, and there's some copy protection, you have to prove you are a human before doing a drawing).
Definitelly a very interesting find. Now i just wish i had any talent for drawings
