Johan Lorbeer is a performing artist. This is his Still-life Performance. It looks like he is floating in the air and leaning of the building. I'll now spoil the illusion. There are no wires here, instead he is held by the very hand he has on the wall. It's like a cage fixed to wall by a pole. The hand is the pole and the cage goes around his body.You can visit his site at www.johanlorbeer.com The site is in German, to see his work click on Projekte and there you'll see the links to them.

In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two mediums (e.g. the atmosphere or ocean) which has the restoring force of gravity or buoyancy. When a fluid parcel is displaced on an interface or internally to a region with a different density, gravity restores the parcel toward equilibrium resulting in an oscillation about the equilibrium state. Gravity waves on an air-sea interface are called surface gravity waves or surface waves while internal gravity waves are called internal waves. Ocean waves and tsunamis are examples of gravity waves.

An amazing video of how forces of nature can be absolutely beatiful.This is a gravity wave. Gravity waves are waves generated in a fluid medium or at the interface between two mediums which has the restoring force of gravity. More on Gravity Waves.
