Audi recently whipped up an interesting piece of advertising in Toronto's Royal Bank Plaza. Partnering with Slot Mods USA, the German manufacturer created a handmade slot car track, complete with a set of scale Audi A4 models. Slot Mods USA employed some pretty interesting tech to create the cars. Using an industrial laser scanner, the company built a digital outline of the sedan before sending it off to a 3D printer to create the bodyshells.
