ARCHIVAL DISCOVERY

Cleaning out the workshop last week, I came across an old color organ that I had apparently disassembled (to see how it worked?) years ago. Color organs, attached to your stereo's speakers, make a twinkling light display - sensitive to sound intensity and frequency. Anyway, I put the device together and found that it still works well.
Inspired, I dug out untouched color organ kits I had purchased 17 years ago....
