greyworld kinetic art

Most of greyworld's early installations were sound based, but recently they have made some great kinetic art. Monument to the Unknown Artist is one of them. It looks like an ordinary bronze statue, but it strikes various poses and even mimics nearby people.

Here is another video which shows the inner workings of the statue. Another great work is The Source.

Wiki: A cube of 9×9×9 (729 in total) spherical balls are suspended on cables that run the full 32 metres height of the main atrium of the newly designed building. These spheres, controlled by a computer running Python scripts, can move themselves independently of each other, forming dynamic shapes, characters and fluid-like motions that reflects the nature of the stock market itself. The sculpture opens the market each morning at 8am, with the spheres breaking free from their default cube arrangement to form elegant patterns and shapes.
