Hi, my guess would be that you are running Gimp v2.6.
This script has been written for Gimp v2.8

Couldn't figure out how to get the animated rain filter to work with this.

I love the effect, I just cant see the entire box on my screen to see all the options. I use the control-alt-arrow to rotate the screen to see everything and then do the same to rotate it back.

Hey PhotoMaster!!! Good to see you.

You need GnuTux's Scrolling Interface script. It puts scroll bars on those dialog boxes that are too big to fit.

Thank You Oregonian! That works beautifully!

I ran two opposing spirals (all black) and merged them onto a white background. Then I used that as a layer mask on another white layer with a photo as the background and came up with this:

You're welcome! What a clever use of a layer mask. Going to have to play with your idea.

That one came out real cool, Greg.

I went in and modified the script to allow "Number of spirals" to be greater than 32 and "Distance from the center" to be less than 8. This is 100 spirals, starting a 2 from center using orange instead of white for the last color.
