Accomodator, 1982

Three 300 Watt bulbs and three 500 Watt bulbs are connected to modulated infrared photocells,

Which are connected to electronic on/off controllers. The 300 Watt bulbs are switched on till one or more person/s intermit one or more of the infrared field/s and one or more of the 500 Watt bulbs is/are then switched on and off according to prescribed intervals which represent certain dimensions of the installation/space.

Relator, 1985

Painted wood, 203x300x300 cm., six 500 Watt incandescent bulbs connected to microprocessors. Three of the lamps are switched on and off in order to spell the words time, space and energy in the Morse code alphabet in certain sequences. Two of the remaining lamps are switched on and off according to a Fibonnaci series. The last lamp is switched on and off in a reverse manner as the two preceding lamps.

Regenerator, 1987

Steel, glass (painted), brass, wire and four 150 Watt spotlight lamps, linked to an electronic circuit and a Geiger counter. The Geiger counter, which is an ordinary battery-run Geiger counter, is housed in a steel box, whose walls are approx 4 cm. thick. When the Geiger counter is encapsulated in this fashion, background radiation is not registered.

The particles, myons, which the Geiger counter registers, stem from the collision of heavy particles from space and particles from the Earths atmosphere. The collision with heavy particles causes a shower of particles from the atmosphere. By adjusting a counter in the electronic circuit from 0 to 999 it is possible to set the number of particles to be registered before the on-off mechanism is activated. For instance, for every 10th particle registered by the Geiger counter, the 4 lamps turn off for the following periods, one period for each lamp: 2 secs, 4 secs, 6 secs and 8 secs.

Three Light Works, 1988

On the wall in the back a work consisting of two computer-controlled lasers, a red one and a green one. Each of the two lasers show eight geometric configurations with different intervals. The two other works are Label 2 (the large structure with controlled 500 Watt bulbs) and an untitled work.

Label 1, 1987/88

Six 500 Watt incandescant lamps connected with microprocessors, suspended in a wooden construction. Each lamp is programmed to spell the word LIGHT, a total of six languages. Each lamp spells the word in one language. By the first run the dot is one second and the dash is two seconds; by the second run the intervals are twice as long etc. The duration of the entire program is about 30 minutes and is the repeated.

Transmitter, 1989

Interactive work with six (2 x3) halogene spots, three modulated infra red sensors, aluminimun tubing, charcoal drawings on the walls, electronics and radio transmitter and -reciever and two powerfull spotlights placed on a facade outside the exhibition space. Whenever one of the infrared fields is interrupted the spotlight, which is otherwise switched on, is switched off (two spotlights for each of the three sections), and the other spotlight is switched on and off according to prescribed intervals.

The on and off intervals are then transmitted in a reverse manner to the two large projectors placed somewhere on the outside of the building, on some other building. The work, or any large or small light work say large public neon-structures, can thus be transmitted by radio or the internet say as a computer program.
