"Drag & Draw" is a new light-emitting pen that will let you make crazy illustrations on any surface, so you can unleash that fantasy of scribbling up your bedroom wall -- without doing any permanent damage.

It was first demoed by Philips at its Simplicity Event 2006 expo in October 2006 in London. "Drag & Draw" consists of a set of digital drawing tools - a multicolor 'Brush', an 'Eraser', and a 'Magic Wand' to bring the drawings to life - and a 'Bucket' to project the virtual drawings onto the wall.
