Looks cool, these would be fun in a childrens science center.
In its most basic form, the Sensacell is a small tile embedded with LEDs, capacitive sensors (like a laptop trackpad) and networking capabilities. Bundled together the tiles can be mounted underneath a translucent surface to make anything from a coffee table to a wall sculpture. The interaction is simple– touch, or even just get close to, the surface and the lights illuminate. Various modes can be assigned– trail, paint, reverse, and others each have different results but are all seriously satisfying in the way they breathe on and off.
