If the function f returns a non-finite float64 value, the SVG file will contain invalid <polygon> elements (althought many SVG renderers handle this gracefully).

Write a non-recursive version of comma, using bytes.Buffer instead of string concatenation.

Exercise 3.11: Enhance comma so that it deals correctly with floating-point numbers and an optional sign.

Color each polygon based on its height, so that the peaks are colored red (#ff0000) and the valleys blue (#0000ff)

Following the appraoch of the Lissajous example in Section 1.7, construct a web server that computes surfaces and writes SVG data to the client.

Implement full color Mandlebrot set using the fucntion image.NEwRGBA and the ttype color.RGBA or color.YCbCr

Another simple fractal uses Newton's method to find complex solution to a function such as z^4 - 1.
