"You're about to see the movie that holds the Guinness World Records™ record for the World's Smallest Stop-Motion Film

The ability to move single atoms — the smallest particles of any element in the universe — is crucial to IBM's research in the field of atomic memory. But even nanophysicists need to have a little fun. In that spirit, IBM researchers used a scanning tunneling microscope to move thousands of carbon monoxide molecules (two atoms stacked on top of each other), all in pursuit of making a movie so small it can be seen only when you magnify it 100 million times. A movie made with atoms"

Apparently IBM are going to buy the rights to Up and Atom and shoot it in 3-D.
A spokesperson for IBM said "one thing we never yell out while making these movies is CUT!";-)
