Mad Science Tee Shirts!
I figured Mad Science (being the best science) might be of interest to the rest of the instructables community. This is my own design, and I'm pretty proud of it. Perhaps you'd like to share your own love of Mad Science by sporting one of these awesome shirts, or giving one as a gift to the Mad Scientist in your life!
As of this posting (December 4, 2013 at 9:00 pm) there's just 3 days and 19 hours to go! If I get just 10 people to preorder they get printed (I'm at 9 now), and if I get more than that then I make a little scratch to fund future projects.
