from POWER studios and Re:Form studios (both out of Sweden)STATIC! is Design for Increased Energy Awareness. They make stuff that investigates interaction design as a means of increasing people's awareness of how energy is used, and for stimulating changes in energy behavior. Revisiting the design of everyday things with a focus on issues related to energy use, they are developing a palette of critical design examples - prototypes, conceptual design proposals, and use scenarios. The coolest one i saw, but there are many more at the
STATIC! website are these bathroom tiles:
What happens is that they are heat reactive... the longer you stay in the shower the less design is left on your tiles. I think that's neat. I mean, who would want to stay in a shower if they know that their bathroom is going to end up unsightly?
