Aura photography from a Chinatown crystal shop. Left, just after chemo, right, today. They have you sit in front of a grey screen, and put your hands on metal sensors, and they take a polaroid with a strange steel camera. The left side is what's past, the top is now, the right is what's coming. A dark aura (a see through one) indicates physical depletion; white light is uncertainty. Whatever you believe, it's fun to do, with a pretty picture besides.
