The World's First iPad Controlled Slot Car Race. Hmm...

This is a behind the scenes look at how Audi and custom slot track builder David Beattie of Slot Mods USA joined forces to create a one-of-a-kind interactive installation in Toronto to demonstrate what Quattro four wheel drive actually delivers. So they scaled down a bunch of Audi A4's into slot cars, built a slot car track and placed cameras inside the cars to allow racers a first-person look as they zip around the track using iPads as controllers. A world first. Pretty cool stuff.
