There is an asymmetry in many tangible interfaces: while phicons can be used to manipulate digital information, the reverse is often not possible - the digital world cannot push back. We describe a tangible pin-board that pushes back by physically ejecting paper documents when they are digitally deleted. This is realized using pouts, addressable pin-like devices that communicate with a Pin&Play board and that can eject themselves by contracting an internal Muscle Wire actuator to trigger a mechanical latch. To demonstrate and begin to evaluate the technology we have developed an initial application of pouts involving a game where online players vote to eject physical pictures from a pin-board.
