Although Mathematica 6.0 gives a General::obspkg warning message when you load the old Graphics`ComplexMap` package, I don't see anything in it that's incompatible with 6.0. The public names Lines, PolarMap, and CartesianMap do not clash with any built-in 6.0 names. And at least on the examples I've tried, you get *almost the same results as when you used the package with earlier versions. The "almost" qualifier owes to the fact that the plots now use 6.0's default coloring scheme for the successive curves. To my eye it enhances things, helping one a bit to be able to trace which image curve comes from which curve in the domain, especially if you make a GraphicsRow with both the domain and codomain, e.g., like this: GraphicsRow[{PolarMap[ Identity, {0, 2, 1/2}, {-Pi, Pi, Pi/6}], PolarMap[ Sqrt, {0, 2, 1/2}, {-Pi, Pi, Pi/6}]}, ImageSize -> 72*8] If you don't like the colors, roll your own or insert the option PlotStyle->Black inside each PolarMap or CartesianMap expression.
