Very cool. Their site is www.nanobama.com.
Barack Obama is larger than life these days. Except, that is, at the University of Michigan, where the president-elect has become remarkably small.
Researchers have created carbon nanotube images of Obama that can be seen only through electron microscopes.
(snip)
Each of the millions of hollow carbon cylinders that make up the incoming president’s image is tens of thousands times smaller than a human hair, but stronger than steel — tiny stuff once of science fiction but now of Nobel prize-winning scientists.
Patterns arranged in the shapes of Obama’s and Biden’s faces, as well as the horizontal flag stripes, are made of metal catalyst nanoparticles. The nanotubes are “grown” like forests of trees on the patterns by 1,000 degree-plus heat in a chemical reaction.
