I just spotted the new Philips: Drag & Draw Technology on Youtube today. A very interesting laser based technology that will allow kids to draw all they want on a wall, then point their magic wand at their drawing and watch as it comes to life. The best part is that unlike pencils or pens, these drawings won't require you to paint over them.
I wonder if there are any practical business applications for a tool like this. I could see it being an efficient way to flowchart thoughts in a meeting if it was articulate enough – say goodbye to that whiteboard and eraser. Interesting.
