thermotiles on designboom

This is really cool, and a good example of how materials can be slightly smarter without being "smart" with circuitry and brains. These thermal tiles won 2nd in a design competition sponsored by designboom.

thermotiles : "Thermotiles two-dimensionalize heating systems into a functional and graphic representation on the wall by silk-screening thermally conductive paste onto ceramic tiles. A copper spacing cross connects the metallic prints at the corners, continuing the circuit and therefore serving as an electrical and constructive element in the heating system."
