The Augmented Shadow light show is one crazy tabletop art light show. The table is an interface where artificial shadows of tangible objects are displayed. I don't have a clue how the artists have done it, but the light show actually revolves around blocks that they move across the table.
When a block moves, objects on the surface of the table appear or disappear. Trees grow according to the amount of light that is shown. These artists must be insanely creative and talented in order to think up such an amazing art piece--watch the video to see for yourself.
