Facebook’s new public API has brought forth a lot of creative effort from external developers, but there haven’t been many desktop applications released to take advantage of its power.

So I thought, what better way to do something fun with the platform than write a MacOS screen saver?

Friend Photos finds pictures of your facebook friends and turns them into a dynamic slideshow.

It makes use of Quartz Composer in much the same way as the Apple TV’s famed screen saver, passing a data structure full of photos and metadata gleaned from facebook into a QC patch and moving them around for dramatic effect.

Let me know if you have any issues, clever presentation ideas, or what have you.

Update:

I’ve written about the creation of this screen saver, along with the early days of the Facebook API, and Facebook’s own embrace of Quartz Composer over here, if you’re interested.
