Jay, Thanks for the PARs & formula for Tippy, Skorpio, Arachnoid and Labster. I had to change the name in the formula definition from "Waffle" to "waffle" to get my version of Fractint to match it to the "waffle" in the parameter lists. - Hal Lane ######################### (\__/) # hallane@earthlink.net # (='.'=) ######################### (")_(")
