Art can be everywhere and in this case of nanotechnology demonstration, on nanotubes. Some guy in a white suit decided to etch the face of Barack Obama on a canvass so small you’ll need an electron microscope to see. Check it out below.

Microscopic faces of Barack Obama made using nanotechnology, and imaged using a scanning electron microscope. Each face consists of millions of vertically-aligned carbon nanotubes, grown by a high temperature chemical reaction. Credit: John Hart/University of Michigan
