There's a new thing under development that may revolutionize, well, something or other: Furry Vision. From the New Scientist Blog:
Here's how it works: imagine the fabric is red and the hair is blue. With the hairs lying flat obscuring the fabric beneath, the pixel looks blue. But applying an electrostatic charge causes the hairs to repel each other and stand on end.
This reveals the fabric underneath and changes the pixel from blue to red. With an array of pixels, Philips says it should be possible to build a furry display that can show complete images.
Just think—pettable signage! Talk about a unique sponsorship opportunity...
