E-paper wool carpet

Patterned carpets are soft, warm, and pretty, but not long after you get them, boring. So use photolyto chipbuilding techniques to make fine conductive strands of little devices with microscopic shutters over the 3 primary colors – a single pixel of color e-paper - each with a unique ID built in. Weave them with ordinary wool or wool-like synthetic into yarn, loop-pull the yarn into a carpet. Send trickles of electricity for both power and data – the data packet is just START-address-r-g-b-STOP to draw an image. Now your room carpet can change its pattern, display photos, text, or whatever you can imagine and realize in software. And it’s still warm and wooly.
