Hi Jim Really nice job..You should do more.. Have you tried using QuickTime to compress your animations? I use the windows version of QuickTime 4 Pro with the Sorenson codec for animations with no sound and the 2x CD setting for animations with sound. The file sizes are very reasonable and the quality is also very good IMHO. I compressed a 228Mb uncompressed animation with 4 sound tracks to 11.4Mb with no visible loss in quality. Ed
