3D-Shadows
Floor 1 | Mindscapes
A tetrahedron on the ceiling or visitors on a floor panel are illuminated by a red and green lamp and thus cast a red and green shadow on the screen behind them. If you look at the shadows of the object or people through glasses with red and green filters, both eyes receive two shadows of the same object that are offset from each other. The brain constructs three-dimensional figures from this.
