2010 Concertgebouw Brugge
A construction of four rails carrying transparent disks. The construction fills a four by four meters space, and the visitor can walk around and through the installation. The disks are fitted with light-polarizing filters, and are rolling over the rails. When they change position and angle, the transparency of each disk changes by blocking or unblocking light. By lifting the rails one side using linear motors, they are tilted in accordance with musical algorithms. Under the influence of gravity, this results in the disks rolling back and forth. This is also a second level at which the installation deals with the idea of polarization in a more general meaning on the word. You can think of a ball on a table, and how to move the ball without touching it. You can lift one side of the table, thereby polarizing the plane on which the ball rests. The plane now has 2 poles, Low and High, and the ball is attracted to Low and repulsed by High. A system without any polarisation, be it in physical or mental space, will become static or stall. For there to be movement, some sort of polarisation is required. I impose 'gravitational polarisation' by tilting the rails. Each rail and disk thus becomes a bistable system with gravitational polarisation.
