Via Wikipedia: Jonathon Keats, experimental philosopher:
In 2006 Keats undertook several new projects, including two collaborations with other species: In rural Georgia, he gave fifty Leyland cypress trees the opportunity to make art by providing them with easels. In Chico, California, he choreographed a ballet forhoneybees by selectively planting flowers on the Chico State University farm, reverse engineering honeybee communication to suggest dance arrangements inside hives. Keats also turned to himself as the subject of a lifelong thought experiment, undertaken through the act of living. To make the experiment scientifically rigorous, he established a scientific control in the form of a high-density carbon graphite block precisely calibrated to match the carbon weight of his own body. The block was placed on display under abell jar at the Exploratorium in San Francisco. And at Modernism Gallery in San Francisco, he applied string theory to real estate development, enlisting the legal framework of air rights to buy and sell properties in the extra dimensions of space theorized by physics. To encourage speculation, the artist created blueprints for a four-dimensional tesseract house that purchasers might use as a vacation home. One hundred and seventy-two lots on six Bay Area properties were bought on the first day of sales.
