Tilt shift effect open source software

Hi, this is a quick post, just to say that I created a simple software (this is the first version, I'll add some improvements) to create tilt shift effect in photos.
Here is the google code project link:
http://code.google.com/p/open-tilt-shift/
This is basically how it works (this photo is from an article of another blog):

 If you want to check the processing code, you can download it from the google code project page.
I hope you like this post, if you have any question comment or send me an email to damianoandre@gmail.com

Bye, Dami
