Donald Lipski and Jonquil LeMaster make artificial tree sculptures. in the spirit of Axel Erlandson, Richard Reames and Dan Ladd pleach trees into forms of their desires. Dan Ladd also has some very interesting molded gourds. Bruce Cannon's (with Paul Stout) slow-moving tree moves just a tad with every presence of a visitor. futurefarmers created a biological robot with photosynthesis as its operating system, CO2 and light as its inputs, and O2 and movement as its outputs. George Gessert breeds new forms in irises (not trees but they are too cool to not mention). Natalie Jeremijenko cloned 100 trees. Jill Reynolds relates us to the mouse, the roundworm, the fruit fly and yeast in her Family Tree. the funniest one has to be the phallic eugenia tree in Santa Cruz.
