The American Chemical Society is holding a video contest to answer the question, "What is 'nano'?" Check out the entries here [3] and vote on your favorite!
The NISE Net's own Anders Liljeholm submitted the above Introduction to Nano video [4]. If you're looking for a more musical approach, check out the Nano Song. [5]
Voting closes on March 24th, but the videos will live on on YouTube.
