An Ithaca College dean is encouraging students to instead think small -- and she's offering a $5,000 prize to do it. The school has invited high school and college students across America to submit a 30-second movie shot entirely with a cell phone.

It may come off like a gimmick, but Dean Dianne Lynch has no doubts about the contest's academic value.

In today's media marketplace -- where cell phones can take pictures, play music and games and connect to Web sites -- it's all about thinking small and mobile.
