Here's an excellent stop-motion video, called "Human Snake" by Get Out and Play. Yes, a viral ad by N-Gage for Nokia, but still neat nonetheless - check out the "making of" in their website:
1,000 people. No effects.
Snake is a mobile gaming classic - in fact it is the most played computer game of all time. So why not get out and play the snake for real?
And no, we are not using any special effects or computer graphics. It is just 1000 people moving in the street - frame by frame and step by step.
