A circuit whose main purpose is to absorb electrical energy (from sunlight or ambient room light) during lit periods, and release it for circuit activity in the dark. The nocturnal activity is generally a light show (by causing an LED or group of LEDs to flash on and off), but can also consist of a pattern of generated sounds. 

More information on Pummers, including a gallery with links to existing creations of this type, is available on the BEAM Bestiary Pummer pages.
