The Spectrum Chart and the Spectrum Drum offers evidence of the discarded society that we all participate in.
It seems the Electromagnetic Spectrum is another form of pollution of the natural environment. Radio and television, hospital X-ray machines, gamma-ray machines at airports and shipping docks all transmit particles into the atmosphere and are potentially dangerous. If you stand under power lines that are close to the ground, you can light up a fluorescent tube just by holding it towards the lines.
What more evidence of the unseen emissions do we need?
