David (or Miguel) thanks for turning me on to ChaosScope! It is an Excellent program - I never knew about it! It is so user friendly I didn't even need the docs. The 3D rotation feature rocks - for the first time I can see what the Lorenz graph REALLY looks like. I knew sooner or later someone would beat my SAX program :( Nice pics in your gallery - I see the Menger Cube there, but I haven't been able to do it yet - gimme more time to figure it out. The Menger image on the web site makes for seriously cool wallpaper also. BTW, IMHO, Zappa sucks. But Rush Rulez! JoTz
