Sooooo, this is a pretty neat project I participated in. There were something like 28000 Moleskin sketchbooks sent out and each person fills it in, using one of the themes as inspiration, and mails it back to the Brooklyn Art Library. They archive them and put them online, send them on a tour that visits libraries in major US cities, and then keep them in the Brooklyn Art Library. Here's a link to their website:
It was interesting sketching based on a theme. The theme I chose was "Science Project Gone Wrong," and as you can see, I used it as a very loose general idea, with some things really having absolutely no relation to it at all... Oh well. It was fun though. I even rebound the book with heavier paper so that I could paint in it, and included a few fold outs! Neat!
