Hey, look at me, actually making a post!
For the last month or so, and up until the end of this month I have competing in a sort of art race with a friend. Our works are at http://artlax.blogspot.com/, and my contributions will eventually all make their way over here.
Shall we just get to a giant mess-o-art?
I just came across a group called Everyday Matters, which posts weekly challenges. I don't intend to join the group, since I'm already a part of too many groups to keep track of, but I do intend to raid their list for ideas.
