Just another idea …
(l) SNOW/RAIN STORM
A script to create an animated snowstorm or rain effect in a scene eg. using pflow. Could have settings for intensity, wind direction, wind force / random windbursts.
(m) SPECIAL DISPLACEMENT
A script for fun to run through a b/w bitmap and randomly (or in eg. jumps of say 10 pixels on the bitmap) create a geometry object (eg. a box) for each pixel eg. with a height or other setting based on the “blackness” of the given pixel (eg. white resulting in tall boxes and grey in smaller boxes).
A script to create foam on top of waves, eg. combining the wave modifier with pflow, or some other method.
