People gather for a flash mob pillow fight

Feathers went flying in San Jose this weekend.

The flash mob in the city's downtown area is seen posted on YouTube. It all started with Facebook and Twitter postings, and ended with about 100 people swinging pillows at each other.

Some of them were dressed up in costumes. A similar event recently became a tradition in San Francisco.

However, city officials launched a crackdown two years ago when the event cost thousands of dollars to clean up.
