SFMOMA invited me to install an environmental sculpture in the the Art of Participation show up Dec 18- Feb 18 2009 in the Public White Cube. My Sand Dune was up for a month as intended then in an exquisite corpse style game, four different people won the right to mess with it, add items and make their own thing out of my installation. Here is a link to the audiotour the SFMOMA did and more comments and pics of the dune. Sand Dune

Here is a photo from my Oct 22, 2007 Mission Lake Project, celebrating the now vanished Mission Lake (AKA known as the Lago Dolores) in the Mission district of San Francisco.

I spoke about the project at a Symposium about public participitory projects at the De Young on May 30, 2007. To understand where we should mark the lines of the lake, in addition to newspaper image archive research, I worked w landscape architects using historical GIS data to create maps for our own use. For a while the maps we created to do my project created were the most detailed available and I was fielding calls about them. Interestingly, since I did this art research project and exposition, much additional art and academic research has been done on this local waterway which mostly agrees with my propositions. While newspaper images show it was navigable, the water level would have varied making it possibly only seasonally navigable as we get only half a year of rainfall here in the bay, some years more than others. Of course it was tidal as are all waterways connected to the ocean. For this project I spoke with the sewer engineers who told me that the corridor along 18th street is still the city’s most intense waterway which of course its underground now in sewers. I wish more images and drawings had documented this waterway at the time.
