Lama concepts, a dutch design studio, has recently introduced a new carpet that incorporates LED lighting into the design. It has been used by Airbus and Landrover but is also available for the average consumer - okay, maybe not average because while I can't find a price on these I am going to assume that it's pretty high. The rugs can be custom tailored to the homeowners needs/tastes. And not only are they are hip and innovative but they are eco friendly too, using wool felt and the low energy LEd lights. For the right space I think this could be pretty fantastic and I imagine kids may find this extra cool as bedroom flooring - no more scary night time trips to the bathroom!
