FedoraUndershirt, I liked where you were going with your sketches but there was no specific design, so I didn't link to yours. And there was another on flickr of an orangutan and a full moon, but I need the original. Email in profile for those with designs you'd like me to post. All designs will follow in comments.
T-shirt designs! Firstly, apologies to all monkeys for taking so long to get this up. I'll post inline images to all the designs received thus far, and anyone with other designs can email them to me or post/send me a link. Once it seems that all designs are in for viewing, we'll set up voting to give everyone a fair chance.
