Here is Animoto, a new cool web service which will grab your pictures on flickr and turn them into a video slideshow. The interface is frankly awesome. I'm not so sure about the usefulness, but here's my test.

The images were automatically grabbed from the finland section of my flickr account.

They also charge you 30 $ for the full version (longer clips). I think that if I'll feel the need for this kind of (frankly cheesy) presentations, i will just use iMovie!
