T-shirt design

Here's a potential t-shirt design me (Sonia) and Diana came up with to wear for Maker Faire, and are a great way for us to look like a professional, unified team. The weird letters on the front say 'WHS' in Greek. We'll probably put the name of the game on the back once we figure out a name. The shirts are approximately $11-12 to order, but Ms. Leppla also gave us the option of DIY'ing it ourselves (it's be cheaper, but probably not as nice looking). This isn't the finalized version, mainly because we need feedback and etc. So please comment your thoughts below (ordering vs. DIY, what should we add/change, would you be willing to buy one, etc.) Thanks!
