This is one amazing piece of technology from Philips, a company that seems to be dipping their hand into all sorts of pots lately.

The 'Drag and Draw' technology allows you to draw on a wall with a digital crayon, without actually leaving a mark on the surface.

I could have used one of these a few months back after spending my afternoon splashing metho on our walls to remove all the crayon, compliments of my 3 year old daughter.

It looks pricey, but that doesn't stop me from wanting one. My kids would go nuts for it.
