I have actually done it that way before. I just have always had a strange preference to see the set as it is being produced, which is far from efficient. Kind of a very elaborate progress bar! Anyway, I have no real complaints about the Tk canvas methods. It has always just been a pet peeve of mine when something as basic and simple as plotting a pixel is missing. My complaint on this goes way back to the ancient days when I had to figure out how to write a plot_pixel primitive in x86 assembler and then build a graphics library of my own so I could have pixel based graphics on my old monochrome IBM XT clone that had a Hercules graphics card in it. Those were the days! Mandelbrot sets in 4 shades of amber-monochrome! ;-) I will check out that book you referenced. I appreciate everybody's feedback on this.
