This is SO cool. In the Web Lab section of Google, there’s now an experiment called Sketchbots. By uploading an image, one of the drawing robots situated in the Science Museum London will start sketching your portrait on a surface. It is filmed in realtime and can be viewed in a YouTube stream.
So if you have any friends or family in London, tell them to go to the museum and watch the robot, upload your picture and they will see it drawing your portrait live.
