The first one is a sculpture made out of metal tubes. As wind passes by it makes the most beautiful sound...
This second a sculpture made from liquid metal.

Ferrofluids, the shape-changing material used in my works, were invented in the late 1960s in the Apollo Program of National Aeronautics and Space Administration (NASA) and are known to be used for forming liquid seals and in electronic devices for computers, AV equipments, and other industrial applications. Recently they have been employed in medicine research.
Basically, ferrofluids appear as a black fluid. They are prepared by dissolving nanoscale ferromagnetic particles in a solvent such as water or oil and remain strongly magnetic even in a fluid condition. Therefore, they are more flexibly transformable as compared to iron sand. It is well known that ferrofluids form spikes along magnetic field lines when the magnetic surface force exceeds the stabilizing effects of the fluid weight and surface tension . In my work, organic shapes are produced by these spikes under a magnetic field that is controlled by electromagnets. Sensing technology and computers are used to make the fluid change its shape according to environmental information. The transformation of the shape and rhythm of the movement is an important aspect of the work.
My first project "Protrude, Flow" used six electromagnets. In this work, the electromagnets sometimes prevented people from viewing the moving liquid. To solve this problem and to simplify the work, I discovered a new technique called "Ferrofluid Sculpture." This technique enables artists to create more dynamic sculptures with fluid materials. One electromagnet is used, with an extended iron core that is sculpted into a particular shape. The ferrofluid covers the sculpted surface of the three-dimensional iron shape. The movement of the spikes in the fluid is controlled dynamically on the surface by adjusting the power of the electromagnet.

Here is a piece that is interactive. It is made up of reflective pieces of wood...
Daniel Rozin's wooden mirror and how it works. Taken from the OU course 'Computers and processors' (T224)
Here is another piece by Daniel Rozin. It is made with disks that vary their gradients.
Circles Mirror is a mechanical sculpture made of 900 overlapping circles with patterns printed on them and connected to motors, computer and video camera. Any person standing in front of the piece is reflected on the piece by the circles rotating to expose more dark/ bright patterns as needed.
