As part of Londons Design Festival Audi has installed 8 robotic arms in Trafalgar square, they spell out messages that are captured on a long exposure camera and can be used by users to send, messages to their friends on the various social networks. Pretty cool hey, well for the robots anyway getting to be outside in the gloriously mediocre weather London is experiencing at the moment.

The installation is designed by Clemens Weisshaar and Reed Kram and will be up from September 16th until the 23rd. Load more to read about this specific installation on Wired Magazines blog. And if you want to post your own message to your friends just head over to Outrace and sign-up.
