Nokia is sponsoring a contest for Xbox Live theme builders, which gives artists the opportunity to have their work offered through the Microsoft Xbox Live Marketplace. Xbox 360 themes let you change what you see on your screen in the Xbox Live Marketplace. Some Xbox 360 themes are free and some cost Microsoft Points to use. To get involved with the contest, artists can upload their work to www.my360theme.com, where the themes will then go through an internal quality review process before the public gets to vote on them. Along with having a theme published, the winner will also receive a 42-inch HDTV, surround sound stereo, Xbox 360 games, Blu-ray player, and Nokia N81 phone.
