I'm curious: what's the problem with a mineral shaped as a human being? Where's the problem with that? Wouldn't it be amazing to see what the forces of nature can create?

To be presice: the tritium itself doesn't glow. It emits weak radioactive radiation which excits a fluorescent dye which then emits the visible light you see. Although it has the same chemical properties as ordinary hydrogen and its level of radiation is - as said before - very low, the use of tritium in e.g. watches, smoke detectors, et cetera is strictly regulated in most European countries. Latest surveys (2008) have shown that tritium can be very toxic when assimilated by human body and should therefore be handled very carefully.
