That would be a lot of colors :-) There would only be 32 different colors since gray 4 and gray 6 will make gray 5, which already exists. The possible intensities from this method are 0, 0.5, 1, 1.5, ..., 14.5, and 15. Hmmm... I guess that only makes 31 grey levels... Also, I don't think a Zip or a Transwarp would make much of a difference in terms of the picture quality... the screen can only be refreshed 60 times a second. -- David Huang | Internet: ifar355@ccwf.cc.utexas.edu | "My ganglion is stuck in UUCP: ...!ut-emx!ccwf.cc.utexas.edu!ifar355 | a piece of chewing gum!"
