Not sure I'd have the guts to wear these, but they are cool! Although this is a case where having PPL is very important - otherwise your kneecaps won't line up!
PS - I have a whole file full of MRI images of my brain (this was back before they went all digital, so they are the giant films; I managed to convince the Dr to give them to me when they were done with them). Now I really want to use them in clothing. =P
