A new SFGate.com article details the adventures of Marty Banks, UC Berkeley professor of optometry and vision science, as he collects optical illusions capable of fooling human and robot eyes. Within walking distance of the campus, Banks finds round trees that flatten into ellipses, restroom floor tiles that seem to bend into hourglass shapes, and an eighth floor balcony from which humans can see objects smaller than a single light-sensing cell in the human eye. To learn more about Marty's research visit the Visual Space Perception Lab at UC Berkley, also known as Bankslab.
