My most recent work

This is a "team" logo for my library's circulation workers (whom I supervise). A couple of them decided they wanted team shirts with their nicknames on them, so I designed a logo. It's not the best I could have theoretically done, and truthfully I'm not fully pleased with it, but I don't really want to work on it anymore right now. I'll see what everyone else thinks. By the way, the number on my shirt is going to just be the symbol for Pi. Shoot, it was either that, 6 and 7/8, or the square root of -1. Pi is probably the most recognizable joke. Now I just need a nickname.
