Hard Rock Cafe in Las Vegas recently unveiled a massive 18′ wide by 4′ tall rear-projection, multi-touch, multi-user interactive wall for showcasing its rock’n’roll memorabilia collection.  Developed by Obscura Digital, a San Fransisco-based “digital design and technology marketing agency,” the wall uses three 1920 pixel HD projectors along with some serious graphics processing power to render a huge number of images and video clips with live multi-touch manipulation.

Additionally, the localized audio system was developed by Technomedia Solutions.

Obscura Digital has a fantastic array of projects on their website, including stunning projections mapped onto building facades (including curving geometries), projections mapped onto cars at an autoshow for an “x-ray” vision effect, and many more.  Check out their demo real for some real eye-candy.
