Now that's a handy magic trick: Observe! This lot, empty but for the world's largest augmented reality marker. Astonish! As a towering skyscraper flickers to life in its place. Wonder! At just how big a camera they must have needed.

The record-setting AR marker—Guinness-certified!—was dreamt up by architects at Königsberger Vannucchi, a Brazilian firm that wanted to give potential clients an augmented taste of what their proposed Fibrasa Connection development would look like. The result: a 360-degree, 3D rendering that beats the heck out of a pile of blueprints. [Augmented Planet via Geekosystem]
