Heh-heh...... I was playing around with it some last night, and I too had chosen the "Busy Sepia Aliens". I can't remember what it was that I had done because I wasjust trying random functions and bumping up the gain here and there, but I ended up with a version which looked almost the same as the original, but it had many more lines. I then got sidetracked by an idea I've been rolling around in my head for a while, and believe it or not, whatever it was i learned during the "sepia" experiment brought me a little closer to getting what I wanted. I'll post a WIP pic in a little bit (so y'all can see I've been doing SOMETHING..LOL). I think this is going to be the thing that finally teaches me some function-type-stuff, and I hope to be able to add something to this "contest" soon, but as far as that goes, I'll probably wait until I have something that's "worthy". I wouldn't reallly say that the above pic would cut it as a sky is concerned, but it does look pretty cool. Can an atmosphere be saved as a .mat? Cheers, Mike
