The Portlandart.net website publishes this picture and many more in an article about artist Robert Irwin. The Los Angeles Times used the photo too, with their review of Irwin's show at San Diego's Museum of Contemporary Art. The picture is of "Light and Space," a composition of wall-mounted fluorescent lights.
Robert Irwin is the man who designed the Getty garden, btw. So there is a shred of a Los Angeles tie-in.
This is "Ziggy Diamond," a scratch-n-sniff wallpaper from a New Orleans company called Flavor Paper.
I would really like to know what scent is in the air at the San Diego installation.
