Asahi Glass (AGC) is showing a new concept called Luminous Touch, designed by Danny Venlet. This is an OLED lighting panel integrated into glass, complete with touch sensitive switch. Quite cool:

The OLED itself is a small circle (probably supplied by Philips as it looks similar to the Dot Lumiblade I have reviewed a few months ago).
