This is just neat. I'm not including any photos here since I don't have permission to post them, but over on The Loom is an excellent, beautiful, nerdy collection of science-themed tattoos.
I just love these -- such astonishing variety! But I have to confess that I feel a little unoriginal now. I've been planning to get a DNA tattoo for some time (expensive project that I can't afford right now, since I want it to go all the way up my arm, down my back, and down my leg), and now I feel like I've been scooped. But it's still unbelievably cool. Check it out.
(Via Pharyngula, of course. Sometimes I think I should just rename this blog "Via Pharyngula.")
