Digital painting kit - a must have for any kid

When I came across this yesterday I found myself wishing I could be a kid growing up now instead of the 80's. A product of Philips called "Philips Drag and Draw Digital Light Painting Kit" allows you to "paint" on ANY flat surface using a special light painting stick, projector, and a light bucket of paint. Sound crazy? It is crazy. Leaving the surface unscathed you can choose any color and draw to your hearts content all over the walls of your house. With the flick of the painting stick the scene actually comes to life and animates itself. I have not been able to find out if its for sale yet or how much it might cost, but when you consider how many walls have been ruined due to kids and their crayons, parents might want to look into this product.
