Animoto is an online service that allows you to create video productions: upload your photos, choose a song, that's all.

They received success when they first launched it as a Facebook Application. In 3 days, the number of users shot up from 25K to 250K

Now they have an iphone application. I've just received an email from the animoto team:

"Create Animoto video shorts on-the-go with our new, free iPhone app. Just snap photos and use the app to turn them into vids right there on your phone. Birthdays, nights out in the city, your irresistible new puppy, at a restaurant with friends…anything you have/take pics of! (Btw--works for iPod Touch, too.) http://iphone.animoto.com"

Good work guys!!!
