T-shirts

The following 2 images are t-shirt designs found on shirt.woot.com. The one is called "minor modifications" and the other is called "in harmony." They are both awesome. But I'm not quite decided on buying anything, yet.




The pluto reference, everyone would understand. But the other one is the harmonic series! Of course I think it's cool, but I don't think many other people would get it. Actually I think more of the physics professors would get it than music professors . . . and about enough of my friends to count on one hand. So I don't know which is more worth it: to teach everyone about the harmonic series, or to just enjoy a joke with everyone about pluto. Hmmmmm.....
