Electric fabric

I read somewhere about some company coming up with a fabric (plastic-based, like nylon or polyester) that is also light-emitting (or very reflective like white fabric paint) so you could program it to show anything you want.

Does anyone know anything more about this?

'Cause they're pretty cool, imagine attaching a keyboard to your tshirt and changing the text on it, I can think of a few good examples:

"I'm in ur tshirt, changing all ur letterz" (with the obligatory photo of a kitten in a sweater)
"Get off my Internet!" (shown when you're passing emos on MySpace on college campus)
"Byte my shorts" (thanks to Long Zheng for that one)
"Life's a bítch and so's my PC"

and many other ThinkGeek.com-esque slogans. Might this put the "slogan shirt" companies out of business?

Dort mund.

Has it not got something to do with quantum physics (rather that being
"electric")?
