Tron: Legacy comes out in just a few painful hours. You've probably seen those Daft Punk headphones, a blue-glowy Razer mouse, and the obligatory armchair, among other insane promotional items. But those earthly objects definitely weren't enough to fulfill the geeky capacity of the branding opportunities that such a cinematic event -- nay, spectacle -- creates. Melbourne-based interactive design company Eness went ahead and built an interactive projection-mapped skate ramp to commemorate the premiere. The Aussies who got to shred in this thing created and destroyed light trails, exploded through galaxies of color and shapes piped straight from the Grid, and had their airtime measured in real time and projected onto the ramp. It's not quite a real-life light cycle battle, but we'll take it. Must-see video after the jump.
