We had a digital whiteboard here at the company I work for. It has tracking implants in the back of the pens to capture the output to a computer.

The amusing thing is that no-one ever used it as a digital whiteboard - it just got used as a normal one for ages, with people not bothering to capture stuff.

The best bit was eventually people started writing stuff on flip charts and then sticking them to the whiteboard with stickier and sticker bits of masking tape. Eventually the board had so much tape on it, that it could never get used for what it was originally intended

So from an expensive digital whiteboard to a normal whiteboard to an expensive pinboard - genius.
