would be handy to just have a webcam pointed at a wipeboard ... then save any snap different from the previous one (sans people standing in the way). and detect certain shapes to auto-link with a URL. also, i would like a pony!

That was my first thought, it seems like the 'take photo/email to special address' step is a bit long winded.

They should just slap a raspberry pi / webcam on the opposite wall and get it to take a photo every 10 minutes.
