I use 7 Sparcstations, but you can use any number of any kind of workstation. I slice the picture into 100 pieces (or any number you want) and dole out the sections to the next available workstation. Each can work at its own pace. When it's all done I concatenate the results, lharc it up, and modem it home to display on my Amiga. It takes a few minutes to do what the Amiga does in 6 hours. If anyone's interested let me know. (Maybe I should post?) Jay Dresser, jdresser@Tymnet.com
