Fun With Atoms: In between experiments, scientists at IBM's Almaden Research Lab in Silicon Valley had some fun creating this image, which is made of carbon monoxide molecules on a flat copper surface. The images were creating by moving atoms to spell "If you can read this, you are too close" Too close indeed, as the letters are just 1 nanometer wide and 1 nanometer tall. The molecules were moved using one of IBM's famous scanning tunneling microscopes.
