The iLog Photosynthesiser converts light into audio allows you to immerse yourself sonic properties of electrical light emitted from the gizmos that surround us. First made in 2007 its a staple in our performances, the second generation Photosynth [2012 onwards], is more relable and safer to use, and comes as kit form. Most amazingly they ues a solar cell as the sensor, but this can also be used to charge itself up. "Charge by day. Play by night." See also the Photosynthonium, a large Log instrument to be used in conjunction with a Photosynth.
