Pinhole Camera
From UO Physics Demonstration Catalog

Description:
We have a essentially a reversed pinhole camera. Light source is in a box and the light that comes out the pinhole nicely shows an image of the bulb filament in a darkened room. It is often nice to describe this as the classroom being the inside of the camera. The pinhole is a small slide of aluminum foil with a hole punched through with a thumbtack. You can make the pinhole larger by simply removing the slide and the image of the filament becomes blurry.
