Crystal zoetrope 2009

Shade Pixel is an interactive display that uses flexible Spandex to represent information. It can be used as an ambient display for its peripherality; non-luminescent nature and simple appearance. The main difference from other displays is that Shade Pixel is applicable to the surfaces of everyday products or to the environment as an interactive skin.



The neat artistic display comes courtesy of Woohun Lee and JinHa Seong of the Korea Advanced Institute of Science and Technology (KAIST). They first created hundreds of animated geometric objects using 3-D animation software, and then engraved those object models into a crystal disc by using sub-surface laser engraving.

That crystal disc ended up sitting on a motor that spins at 120 rpm, in a circular bar stool configuration. A group of 25 LED lights surrounding the crystal disc help create the animation by blinking on and off at 80 hertz. People can play with the device based on a touch sensor array, which allows users to control the direction of the spinning spiral and its brightness.
