Moving color are a company that specialise not only in temperature sensitive glass, but other materials that are altered to be temperature sensitive. Their website www.movingcolor.net is amazing. They showcase anything from shower tiles to temperature sensitive guitar picks. I just think that it is incredible the technology that they are using and that they have been very innovative in showcasing different ways of using the same material.
Below is an image of one of their many glass tiles. I sourced this from Freshome, Interior Design and Architecture.
