Now, a growing group of writers, musicians, visual artists and videographers is turning this Wikipedia-era philosophy into online collaborative art.

Twitter users are banding together to write an opera for London’s Royal Opera House. Bands like My Morning Jacket and Sour, out of Japan, are turning to fans to help film their music videos. Programmers are pulling quotes from online social networks to make automated poems.

More than 50,000 animators are divvying up work on an upcoming animated film called “Live Music,” and amateur videographers are re-filming “Star Wars” in 15-second bites.

This crowd-sourced creativity online is putting a new twist on traditional ideas of artistic ownership, online communication and art production.
