World's smallest abacus: http://www.zurich.ibm.com/pub/hug/PR/Abacus/ Moving about individual molecules using a scanning tunneling microscope. I don't even know what one of those is, but it's nifty.
Nanotechnology is a popularized word to describe the interactions and creation of structures on the atomic level. Chemists will tell you it is chemistry, and certainly from their standpoint nothing new. Physicists will tell you that it is materials, condensed matter, or a variety of things and they see a system of incredible complexity. The blind man will tell you it is something they can not see. The honest may say its everything. I hope it is a sculptor that can shape itself.
