OK, now this cool. Yesterday, as part of the Rhythm of London festival, a busking competition concluded. Winners will get a free one-year license to busk in the London Tube. Competitors uploaded videos to YouTube (haha Tube for Tube), where people vote for their favorite buskers. Now that is crowdsourcing. There are two easy ways to see the submissions: The busking competition group and ROL2010 tag.
Above is the submission from Hanno Rigger, Raphael Lanthaler and Vince Welch.
