A method and apparatus are provided for using microvariations of a
biological living organism to generate a sequence of environmental changes
perceptible through one of the human senses. The method includes the steps
of transforming microvariations within a living organism into an analog
electrical signal and generating the sequence of environmental changes
perceptible through the human senses based on said analog signal. The
sequence of changes can include the generation of music based on the
signal, or the control of lighting, aromas, or air movement in the
environment of the organism. One example application is the generation of
music from electrical microvariations detected in a house plant.
