Seattle-based Treemo is launching a contest on its social networking site made for mobile phones.

The winner will receive tickets to a Velvet Revolver's concert in New York on Aug. 18. The plane tickets will be provided by another Seattle company, Farecast.

Participants are asked to send in videos, photos and essays on Velvet Revolver's new album -- Libertad, or freedom. Submissions are made by mobile phone.

There's already quite a large collection of entries on the Web site. There are several pages of thumbnails, where you can view pictures and text messages people have sent in representing freedom, including pictures of snowboarding and flowers.

To enter, you must register for a Treemo account or log in to your existing account, and then upload photos, videos, audio or text. The entry must be tagged "libertad." Winners will be decided by a combination of number of views, favorites, comments and shares, as well as a final vote among judges.

Brent Brookler, the company's CEO, said so far Treemo has more than 50,000 registered users and 95 percent of its traffic is coming from mobile. He added that Velvet Revolver has band members from Guns n' Roses and Stone Temple Pilots.
