i've been looking on google, but it brings me to Adobe ones, i was wondering if any of you guys had them.

I'm looking for real beginner stuff to get the feel of stuff.

I've tried a couple of the first ones, but its like smudge the picture and then put the main image back or something and i don't know how to do that. I've watched a couple of videos of the tools, any other suggestions?

Did you check this signature database ?
Many awesome tutorials i really recommend for anyone

Here is a very simple and fun tut you might want to start with
