Just added a new free script. It's a google page rank checker and backlinks calculator from multiple search engines. As my other free scripts, this one also is based on PHP and jQuery and also, I used FaceBox plugin for adding functionality for displaying a overlaid window with the results for some eye candy.
You can test it here:

Unfortunately, this script is not yet available for download because I'm still working on it. Feel free to give me some feedback on it, to help improve it.
Thanks and ENJOY!
