Early bio-sensing electronics wiz Tom Zahuranec invited an audience to a special radio event situated in the KPFA Music Office. Tom had wired a Rhododendron with liquid electrode sensors which were amplified and fed into the oscillators of a Buchla Synthesizer. The plant itself acted as a conduit between the studio environment and supposedly- the psychology of surrounding participants. Far-out commentary was provided by Tom and curious listeners who dropped in on the happening.
Images of Tim and his 'plant amplifier' can be found at Data Garden.
