I submitted this to the Tee Virus workshop and thought I'd share it here. It's a math-centric design and hopefully humorous to one or two of you Sifters.



Here's a follow-up inspired by demon_ix's comment below:

If you haven't or don't on a regular basis, please help us by at leaving your comments and casting your votes in the Tee Virus Workshop. There are a few designers there who often get very little to zero feedback on their creations and it'd be enormously appreciated if you'd just lend us 2 minutes of your day. Thanks for your help Sifters!
