Spot is a lightartwork on a facade of a cultural center in Lörenskog Norway. The work covers the whole roundshaped facade of the building (25 x 100 m). It is made by computer programmed led-lights. The barckets of the leds head the big round shaped light spots on the facade. A compouter program makes the lights move on the facade; sometomes horisontally like the traffic on the motorway beside, sometimes like a very slow wave on the wall.
