Thanks PhotoMaster, i threw it right into my scripts folder. =)
Its a handy script for creating crops with digital images...enhances the viewers attention if the objects you want them to see are on those guide intersections. =)
Just thought i would throw that explanation in there for anyone who didn't know what Rules of Thirds meant.

Thanks again... wonderful script

I saved the script and also the Golden Ratio guides from this search. I don't know what to do with the results. Must have something to do with photos (?).

I've read just about anything and everything I can find about the golden ratio and used it in designing clothing patterns.

Late edit: Never mind, I'm doing the Rubik's Cube tut and see where it goes. :-D

The rule of thirds is basically a guide that says when you keep your subject along these theoretical lines to make your images more interesting. It's big in photography, but also in painting and sketching. It's a good tool for other things as well.
