Great effect! Thank you, Peter.
And a special thanks to FX Mahoney for taking the time to develop this & provide such an excellent tutorial video.
On top of all the wonderfully artistic applications this plugin serves, I thought of one that might not be so obvious...
While watching the video & seeing the crowds running the marathon, I was thinking this could also be used to obscure identities or protect privacy instead of facial blurring. Since we have such great control over smoothing, contrast & all the other attributes, I think this method could obscure a person's face enough while maintaining the aesthetics of the scene.
