Sony Ericsson asked us to come up with a way to promote their new phone which is fitted with the 'Motion Sensor' function - it senses movement made with the phone. The problem was that technologically it had already been done with Nintendo's Wii. So we were inspired to do a promotion using the phone for air guitar. We set up an air gaming federation and a contest, and in response, we got 70 decent videos, which was much more than we expected. Success! Now we're working on the next project - 'Air Football' for FIFA 2009."

When I found out about the competition I thought the idea was absolutely brilliant. I already knew of air guitar but with air gaming there's loads more to do. At first we wanted to use a group sport, after we'd seen the rugby version, but it was too complicated. When we thought up the idea of scuba-diving, we found it hilarious. We needed a lift that took a long time so we went to the business district of Paris one afternoon with a wetsuit and a peg. We filmed it with a digital camera, in 30 minutes, with the security guards watching us. It was so funny!"
