We didn't think too much of Obscura Digital's multi-touch hologram when we spotted it last August, but evidently the company has been working overtime in order to outfit Hard Rock's newest cafe with a monstrous interactive video wall. Hard Rock Cafe Vegas Strip is the chain's second venue in Sin City, but it's far and away the one to hit if you're a self-proclaimed nerd. Aside from having access to a number of Microsoft Surface-based installations, you'll also spend a good bit of time navigating the Rock Wall. The 18- x 4-foot touch wall (video after the break) enables up to six guests to simultaneously surf through the outfit's expansive memorabilia collection, with options to zoom and flick through oodles of images. Obscura claims that it just might be the world's highest resolution interactive display available to the public, with a trio of HD projectors beaming the content from behind the glass. Not like you really needed another excuse to add one more HRC shirt / pin / glass to your collection, but feel free to express your gratitude in comments below.
