Hi Paul,

Glad the instructions were useful!

I know it is possible to batch process with the GIMP, so I imagine you could create a filter or a script or something to apply this effect to thousands of images, but I've never done it myself, so I'm afraid I can't be much help there. If you do succeed, please post a link here, I'd really love to see the resulting video, I think it'll be very cool!

Bart.
