Digital Home Thoughts: Whiteboard Photo from Polyvision

"Whiteboard Photo lets you take snapshots of your dry-erase (dry wipe) board, flipchart, chalkboard or document with your digital camera and convert them into crisp, perfect images in seconds. Whiteboard Photo uses proprietary image processing algorithms to compensate for the geometry of your photograph, correct the colors, and clip the borders so that you get a perfect printout of your board every time. You don't need to worry about the angle of the camera, the lighting, reflections, or even small print. Whiteboard Photo can create brilliant hardcopies in less than 30 seconds."

Looks like a niche application, but a very cool one at that.
