Blendid, which is a cooperation between David Kousenmaker and Tim Olden has developed wireless controlled pixels based on LED technology. With these small light objects, or Wixels, Blendid creates light sculptures. Every Wixel can change into any colour of the rainbow. The Wixels can be programmed collectively or as a cloud, but they can also react as an interactive whole. Associations with school of fish or a swarm of birds come to mind, behaving as one complete organism. Connected to sensors, a Wixel cloud can change into colours that are generated by all kinds of parameters. As the size of the original Wixels appeared to be too small to have sufficient impact, Blendid opted for larger light bulbs. A solid system to hang more than 100 bulbs was installed in the Tschumi pavilion.
