Elizabeth Hickok depicts various landscapes of San Francisco using jello. This one above is the Bay Bridge.
"I make the landscapes by constructing scale models of the architectural elements which I use to make molds. I then cast the buildings in Jell-O. Similar to making a movie set, I add backdrops, which I often paint, and elements such as mountains or trees, and then I dramatically light the scenes from the back or underneath. The Jell-O sculptures quickly decay, leaving the photographs and video as the remains."
