in the house i grew up in, when the blinds were down in my window i would have a camera obscura for like half an hour each day. it made sick days more tolerable.
Once I hitched a ride on the back of a empty meat truck, so it was pitch black, some minutes in my eyes got used to the dark and started to notice a projection on the front wall and I could somewhat see what was behind the truck, even got to id car models.
