Here is a great, fun, creative idea – I’m really interested to see how it plays out. From KOCE-TV (a PBS affiliate) website:

Film on the Fly! is the latest and greatest in mobile filmmaking challenges!  On the day of the contest, you’ll receive a text message with a secret story prompt for your video.  You’ll then have up to twenty hours to make a mobile phone video and post it to YouTube. Since this is a global challenge, you’ll be able to see mobile videos that are created from all over the country, and maybe even the world!
