Dens and Naveen appear in Gap’s holiday promotion to benefit Camp Interactive

Gap has launched their holiday Want campaign, with celebrities describing what gift they want to give the world. Foursquare co-founders Dennis Crowley and Naveen Selvadurai make an appearance in the video. Their gift? “Exploration and new experiences.”

For each “like” a video receives on Facebook, Gap will donate $1 to the charities selected by the celebrities. Crowley and Selvadurai appear in the “Anthem” video. They chose to benefit Camp Interactive, a non-profit “that empowers inner-city youth through the inspiration of the outdoors and the creative power of technology.”

There’s also a bonus hidden at the end of the video for viewers: a 30% discount on a single Gap item in stores this holiday season.

It’s not the first time Crowley and Selvadurai have supported Camp Interactive. A deal with Pepsi last December offered a donation for each foursquare checkin in New York City. Their NY Marathon runs on Sunday also benefited the charity.

The other celebrities participating in this campaign are:

• Model and co-founder of FEED Projects, Lauren Bush, supports FEED Projects;
• True Blood’s Ryan Kwanten supports City of Hope;
• Comedian, writer and star of NBC’s Community, Donald Glover supports Community Connections;
• Actress Yaya DaCosta supports Women for Women international;
• Social Media whiz Alisa Leonard supports Goods for Good;
• Style blogger Susie Bubble supports Shelter England;
• Broadway’s “Spider-Man,” Reeve Carney supports Partnership for the Homeless;
• Dancer and choreographer Benjamin Millepied supports Baryshnikov Arts Center.
