I have filters/animation but no settings. I thought I had GAP installed right. dear me.
I believe that is referring to the following Script:

While it can be a challenge to create a dynamic gradient/pattern/whatever fill, GIMP's GAP makes it fairly quick work to actually perform the fill. If you start with an animated ballet dancer on transparent layers, just split that image into frames ("Video->Split Image to Frames") and then do the following:
"Video->Frames Modify -- Function: Apply filter on layer" and choose the "plug-in-wr-color-levels" filter with "Apply Constant". Set the Low Output value to "255" (regardless of the range of input values, the output range will be 255-255; that is to say, the output will be white).
You can now use "Video->Move Path" to add a layer to each your frames containing whatever pattern you wish to use as fill and using whatever motion transformation you wish (you might even use an animation/video frames for your fill pattern). After the new layers have been added to your frames, you can use Frames Modify to perform whatever additional filtering you wish to the layer.
The next step is to use the first layer (the one with the white dancer) as a layermask on the pattern layer. This is done with the following:
"Video->Frames Modify -- Function: Layer Mask->Copy mask from layer below". (Since the bottom layer does not have a mask, a grayscale version of the layer itself is taken as the mask. Transparent regions are considered black, which is why we had to convert the dancer to white.)
The following GIF shows the result of using rendered diffraction patterns as my fill:
