Blizzard is now accepting submissions for three BlizzCon 2011 contests. Winning these contests will earn you a ticket to this year's convention as well as other prizes.

The fan art contest tasks gamers with creating original art based on the Warcraft, StarCraft, or Diablo universe. The first place winner will get a One DellTM UltraSharpTM U3011 30" Monitor with PremierColor. The second place winner will get an NVIDIA GeForce GTX 580 video card as well as a copy of Adobe Photoshop CS5. Third place will get Adobe Photoshop CS5.

To enter the movie contest, you'll need to create a film with footage from Blizzard games. The film can only be three minutes long so keep it snappy. Cash prizes of $2000, $1250, and $750 will be doled out to the three winners. The first place winner will also get an "Oswald" statue.

The original song contest will task you with writing a two-minute or less song based on Diablo, StarCraft, or Warcraft. The cash prizes for the winners are $2000, $1000, and $500. All three winners will get a copy of Echoes of War : The Music of Blizzard Entertainment autographed by Blizzard composers.

The deadline for all three contests is August 29th. Check the links above for guidelines on submissions and other fine print.

BlizzCon 2011 will run from October 21st and 22nd. As in previous years, it will be held at the Anaheim Convention Center. Winning entries from each contest will be performed or displayed at the convention.
