The Barack Obama campaign has a nice viral video campaign on youtube called "Yes we can." Since it was added on February 2, this video has been viewed over 4 million times. It is a great example of how inspiration sparks creativity in order to push positive change. Will.i.am of the Black Eyed Peas and several other artists such as Herbie Hancock, Esthero, John Legend, Ed Kowalczyk and Tracee Ellis Ross, made this project happen.
Moveon.org has been using this video and urging people to get out and vote by using the video virally.
