This is me wearing my Low-Poly Mask made out of dark cardstock with glow-in-the-dark tape applied along the polygon edges. I'm very happy with the results, and believe me, it looks cool in person. I don't know how many photos I had to take to get a couple good shots, due to the extremely slow shutter speed. Some of the "failed" photos in which I moved too much are kinda' interesting, but not good enough to share.
