Light Columns

1971

3 columns, each 56.5 x 7.5 cm diameter

Aluminium base and electric motor, ground aluminium cylinder wound with:

(1) Enamelled copper wire.

(2) Nickel chrome wire.

(3) Purple enamelled copper wire.

The line of light appears to move simultaneously up and down. This may at first seem a contradiction in terms. The line behaves as one continuous movement but simultaneously within itself contains separate moments of motion.

The oscillating line of reflected light on each cylinder acts as a system of signals that describes spatial changes occurring on the surface of the cylinder.
