"For Alexandra on the eve of her 29th birthday..." A wall drawing
For Alexandra on the eve of her 29th birthday: The path of the sun projected onto the south wall of Room 2250K, Broad Art Center, UCLA, Los Angeles, California, United States of America, ~118°26’W 34°05’N, seen from a distance of about 90” from the wall, drawn in real time in 10 minute increments on December 4, 2011 from 1730 to 2200 GMT, interrupted by chance from 1830 to 2040 GMT is a wall drawing I created at UCLA's Design | Media Arts Program.
I used data from the United States Naval Observatory (USNO) to plot the location of the sun as it would been seen from 118°26'W 34°05'N on December 4, 2011. I combined this data with measurements of the geometry of Room 2250K, Broad Art Center, UCLA and used a bit of homebrewed analytics to project the path of the sun onto the south wall of the room. I then drew this path in real time in 10 minute increments — in other words I drew a point every 10 minutes representing the position of the sun at that moment, and then connected these points to form the arc.
Although I intended to be in Room 2250K throughout the day on December 4, 2011, I was called away. This time is represented by a broken line in the arc.
This piece is a new direction in a path that I started down many years ago. It is a drawing that at the same time records, time, place, activity, and thought. I hope to do more soon.
