Nanobama

How to build a president from carbon nanotubes.

John Hart, assistant professor of mechanical engineering at the University of Michigan, has created the president-elect’s likeness using vertically grown carbon nanotubes and imaged them with a scanning-electron microscope. His gallery–and instructions on how to make your own “nanobama”–are at flickr and nanobama.com. Hart says that he made the nanobamas to promote interest in nanotechnology research.
