Here's some pretty slick glass/light technology called LightPoints, one of many architectural materials developed by Schott. Not specifically designed to be interactive but with some cleverly placed sensors and DMX control system for LED switching there's potential for some very nice interactive architecture indeed.
A pane of transparent glass conducting electricity is equipped with LEDs. Using the PVB (Polyvinyl Butyral Foil) laminate method, a cover glass is then added. The LEDs available in white, blue and green emit light in both directions.
The red and yellow LEDs radiate only in one direction. The power (low voltage DC) is supplied through conductive circuits on top of the glass that are almost completely invisible.
