Scientist John Hart created a remix of Shepard Fairey's Obama poster from 150 million carbon nanotubes, each of which measured tens of thousands of times smaller than a human hair. That sure is a lot of tiny Obamas. Snip:
Even then, the finished product is only half a millimetre in diameter and almost indistinguishable from any other garden variety micro dot – unless you happen to be looking at it through a microscope.
The magnification reveals tiny, three dimensional "carvings" of the now ubiquitous polarised image of the president-elect originally created by street artist and graphic designer Shepard Fairey.
The "Nanobamas" were created by a team of researchers led by Hart, an assistant professor in the Department of Mechanical Engineering at the University of Michigan.
