The Hairlytop Interface is an interactive surface display made of soft solid-state actuators and optical sensors which react to light. Jointly developed by the University of Electro-Communications and Symphodia Phil, when placed on an iPad that is playing a video, it moves organically, like a living thing, in response to changes in the brightness of the screen.

"One feature of this system is that the motion is very cute, like that of an animal. Another feature is that it can be used extremely freely in terms of design."
