You may think that once you've seen one building
turned into a massive billboard
you've seem them all, but that would mean you probably haven't seen the so-called "Media Facade" now adorning Bayer's former HQ in Leverkusen, Germany. Built by ag4 media facade GmbH and GKD AG, the massive display apparently consists of 5.6 milion LEDs that cover the entire 17,500 square meters of the building, and which can be lit up at will to pump out gigantic advertisements worthy of any science fiction movie. You'll note this is the former Bayer headquarters -- it seems that the promise of 'round the clock ads visible for miles around saved the building from the wrecking ball. Head on past the break for a video of it in action, and a second showing the facade being constructed.
