E-ink technology is known to my geek audience, they are now found in Amazon Kindle and many other products. My first brush was via Motorola F3, still used by my dad. More interestingly, Toppan Printing has created huge 1 x 3.2 meters posters made with E-ink technology. If I could get a wall converted into e-ink, or all, I could change the wall paper ever so often as well as watch TV right on the wall (when the fast refresh does come to happen with e-ink).

On the other hand, Spray-On Solar-Power Cells are true breakthrough; using nanotechnology you can now paint it on any surface & when it dries becomes plastic and generates electricity. And can be used even under cloudy weather conditions.

Add an Adruino somewhere and you have a perfect geek wall painting! :D Or may be something like the Noteslate, only a very large one! :)

BTW, I am eagerly waiting for the Noteslate to graduate from the echelons of vaporware to reality. I have been enamored by the idea ever since I saw the Boogie Board at a Brookstone last year, no not the surfing kind, an LCD based chalk board kind of tool that does not store the stuff drawn on it.

h/t to Lisbeth Shaw for triggering the e-ink idea when she suggested me to paint the walls of my new villa with it ;)
