The Downsizing of Obama

There's an interesting article in Wired magazine about Obama portraits sculpted using nanolithography by University of Michigan mechanical engineer, John Hart. Each Obama face is composed of 150 million carbon nanotubes and measures half a millimeter across:



I don't know what this new technology is good for, but I do know it will find a use. I think back to this example:

When looking at the new invention of an electric motor, Prime Minister Gladstone asked Faraday the inventor "What good is it?" Faraday replied "Some day you will be able to tax it."

Here is more nano tech for the enthusiast: Wired magazine has an article on Self-Assembling 3D Nano machines. It discusses interesting new technologies such as the following:

In May, scientists at Copenhagen’s Center for DNA Nanotechnology described a DNA-based box with a lid that stays locked until exposed to a DNA-based key, which prompts the lid to pop open and potentially release a drug. A team led by McGill University chemist Hanadi Sleiman is also building DNA cages and nanotubes for delivering treatments.
