Hyposurface

Hyposurface is a wall that physically moves.  Combining hundreds of mechanical pistons under a fabric and plastic surface, almost any design can be displayed by raising and lowering the pistons.  Patterns can be programmed to sync up with a variety of input - sound, movement, even an internet feed.  More about Hyposurface and its designer Mark Goulthrope can be found at Hyposurface.org.
