i don't think it ...
i don’t think it was actually one of these that i saw demoed a few weeks back, but it was pretty similar. it’s a way of drawing on whiteboards that draw pictures on your computer screen at the same time. i was pretty impressed by it.
now it looks like internet enabled pens are coming. i’m not sure they’re as instantly and obviously useful as the whiteboard version but i still think that they’re a great idea.
