I hadn't realized that you could use "0" - I figured "1" was the 
smallest value that would actually wait, anything smaller would not 
require a wait.

Before your earlier improvement (i.e. when the points of the graphic are 
updated every time round the loop), it was never that fast (at least on 
my laptop). Now I get
  0 - just appears almost instantly
  1 - draws smoothly and quickly, like sweeping through each "arm" of 
the drawing
  3 - draws smoothly, you can watch the "pen draw the lines"

Feels like time for another slider control ....
