I have a set of actions that use the Oil Paint filter in PSCC which is not a part of CS3, so I tried to find an old one and Alien Skin is what I came up with. I am amazed at what these plug in do in the default settings. Here's a couple of examples (in close up).
|Default "Oil Paint, Abstract (colorful)" filter with|
a minor tweak of making the strokes shorter.
|Default "Oil Paint" filter with no tweaks. Dig the texture!|
