Hi sjm,
I wrote the action you're referring to. You can find it here:
Kaleidoscope action.
What problem are you having? Did you upgrade
PS? I had to write a version of the action for each version of
PS from 5.0 because of different naming conventions for the layers, so perhaps that's what you're running into? If not, please describe the problem and I'll see if I can figure out what's going on.
