Billed as "the largest worldwide festival of films made for mobile", Mobifest (in its second year running) is now accepting digital submissions through their website.

The rules are simple: keep your movies under 60 seconds, and shoot for the "tiny" screen -- that means you should stabilize your camera as much as possible and mainly go for close-ups. And lastly -- something most folks don't know -- you can shoot your brilliants flicks on anything you like, not just cellphones.

The deadline for submissions is Oct. 31, 2007. Chosen entries are eligible for awards and will have their movies showcased at the Isabel Bader Theatre on Nov. 20, 2007.
