As I work for BT this was on the BT news the other day. I think it's pretty cool.
The worlds largest picture of London , 320 Gigapixels put together from 48K photos.
You could win an I pad if you manage to spot one of the Buzby's in the picture. I have manged to find all three . Not very busy at work at the moment.
You will also see some of the errors that have been made when tiling the photos together resulting in cloned people and vechicles chopped in half.
