Animation FX
Animation FX are a series of imaging effects that can be applied to images.
A simple movie showing how to use the AnimFX scripts is here. This movie includes the AutoGoo effect.
The source of the demo movie above can be downloaded here (~600k) - though not all the AnimFX scripts are included (BlueMeanies and KeefRichards are not included). If the full demo is too big, you can grab just the AnimFx scripts in a Director 8.5 cast here.
