Niklas Roy, possibly best known for his robotic curtain, has created a new project that combines an analog black and white video camera with a thermal receipt printer. Combined the two form a sort of Frankenstein Polaroid camera which he calls Electronic Instant Camera. The camera prints the photo directly to the receipt paper as the photo is being taken. The process can take up to three minutes, during which the photo subject needs to sit still the whole time.

Definitely not practical, but interesting.
