The above picture was taken in the offices of Appency, a PR firm that helps market and sell mobile apps, including iPhone and iPad apps. It's indeed a big iPad, though instead of a functioning touchscreen, the whole thing is actually a working whiteboard painted onto the wall. Founder Aaron Watkins tells TUAW that the studio moved into its new offices a couple of months ago, and decided to use a substance called IdeaPaint to literally paint a whiteboard on the wall.
Originally, they wanted to paint two whole walls with the stuff, but it's pretty pricey, so instead, design intern Lorin Estes had the idea to turn the whole thing into a giant (to scale, we're told) iPad. Pretty awesome -- though not quite as portable as the real thing.
