Thanks, Bill… I’m afraid I didn’t save the project file. Just tinkered with it until I felt it was interesting, then I recorded it and added a little music. I took a picture of a field stone bench I have up in my back yard, then reduced the size and cut out a block of the stones and pasted them in a 256×256 frame with an alpha background then started playing around with many different emitters until I had something I thought was interesting.
