Super Cilia Skin by  Hayes Raffle, Mitchell Joachim, & James Tichenor is a tactile and visual system consisting of an array of actuators that are anchored to an elastic membrane. These actuators represent information by changing their physical orientation. See Paper

Each actuator is a felt-tipped rod with a magnet at it’s base. The rods are anchored to a silicone membrane with two plastic nuts. These actuators oscillate in response to a magnetic force below the surface of Super Cilia Skin. This force alters the angle of the actuators on the upper surface. The prototype of Super Cilia Skin was designed to be operated by the Actuated Workbench which uses a computer to control an array of 128 electromagnets, smoothly moving magnetic objects on its surface.

Applied on an architectural scale, Super Cilia Skin would act as a display surface reflecting changes in local or global conditions. On a smaller scale, an object surrounded by Super Cilia Skin might propel itself across the floor or be able to propel objects across its surface.  via Karen at Mr. Watson
