Lightblueoptics, a start-up company that makes a interactive display that converts any surface into touch screen is using Flash Lite for UI. Take a look at press releases from Elecronics Weekly and Geeksmack. They show pictures of of keyboard being projected onto any surface. The display works as any other keyboard and responds to touch as needed. The keyboard is projected using Flash Lite, an IR sensor senses the movement of your finger and the projection technology is based on holograph. The gadget is being demonstrated at CES.

This is pretty kool technology. Conventional keyboards are bound to be obsolete in the future and perhaps something like this will replace it.
