Downwindsong - 1997
This machine responds - with a dance of moving light - to ionizing radiation. It interprets for the senses some of the form of an invisible activity. Where I live, hits from background radiation average about one-per-second in chaotic intervals. This is my second machine built around a Geiger tube, and I have plans for about fifty more. No attempt has been made to calibrate this machine. It is quiet when a lead shield is around the detector, and it becomes very active when exposed to known radioactive objects.
