Plotting points every second or so

Questions
1

I am trying to plot a calculated point ( the midpoint between points) every let’s say 1 second after pushing an action button

  1. User starts by picking an ordered pair. lets call it point A
  2. CL chooses a random point from a set of three fixed points and then
  3. midpoint is plotted call it (B) , after 1 second the midpoint of last point plotted B and one of the same fixed points is plotted.
  4. continue for as long as you want

Any help?

Thanks, Gregg Klein
