Here is a selection of PS action scripts that i have made or modified from existing ones. They produce some great effects. Try them out and let me know what you think.

INSTALLATION
Download the action set (right click and save target as)
Assuming a default installation (on a PC), put the action into:
C:\Program Files\Adobe\Photoshop 7.0\Presets\Photoshop Actions\
From the Actions palette menu ( ), select the name of the .atn (which should appear near the bottom of the menu, in alphabetical order)
Note: If the action does not appear in the palette menu, choose Load Actions; navigate to the appropriate path (from step 2, above) and select the .atn
