A new nightclub in London, twentyfour: london, is designed to appeal to the high-tech "wouldn't it be great if holodecks were real" side of the population: it has walls that can change and morph into whatever you want them to be, via projection technology. A canyon? You got it. A beautiful beach at midnight? You got that too. Want to ogle models strutting the catwalk? No problem. You can even bring in your own videos and pictures, so it really is "whatever you want." Other features the high-tech nightclub offer include drinks that notify the bartender when they're empty and interactive experiences like a virtual koi pond.
