2013 | RGB LED, Stepper Motors, Electronics, Wood | 58x41x12in.
The RGB LED in this machine can be programmed to move precisely in a prescribed pattern. By documenting the moving LED in long exposure photographs, the invisible history of the light is captured.
Many of the images made with the machine are plots of Cartwright’s track as recorded in his Latitude and Longitude Project. Different colors represent the various years of the project. These images show movements within the confines of cities Cartwright has lived. Images can be exposed with multiple years in one image or separated out year by year. Increases in luminosity show patterns formed from repeated excursions along the same track.
