Lewis,
Sorry you feel I stole the idea from you. In truth I didn't, and I'm sure there are many people who realized you could use the blur filter with fog to simulate the effect when Adobe released the blur filter, I think in CS2. That's when the idea came to me anyway.
You should get full credit though for sharing the idea here first though, so many props to you.
It's a fun effect, hopefully we'll be putting out more videos on creating effects in PS. Cheers!
