After you download the script to your scripts folder and refresh your scripts (Filters -> Script-Fu –> Refresh Scripts), you'll find the new script in the menu under Script-Fu> Darla –> Saturation Fix.
Creates an image of rainbow coloured circles to give a plasma-like pattern. Also comes with an animation script that animates the pattern. Frames are saved as layers. Choose min and max speed and circles are randomly increases/decreased in radius according to the set speeds.
TODO - Save frames as XCF files compatible with GAP.
This is a script that is based on the lightning tutorial (http://gug.sunsite.dk/tutorials/tomcat9/). It was tested on GIMP 2.4 (so, using the new scheme engine).
It comes with two versions; one that creates an image of lightning and another that creates an animation (using layers as frames) of lightning with parameters to modify the turbulence so the lightning bolt appears to dissipate over time.
Pandora simplifies the process of stitching together a sequence of panorama images.
Load all the panorama pieces (in order) as layers inside an image (suggestion: make a new image then "Open as Layers" and select all the files). Then run Filters->Combine->Make Panorama.
You still have to do the detailed matching by hand, but Pandora calculates the needed image size, moves all the layers to approximately the right position and creates appropriate layer masks for fading each image into the next.
