Declare the Sleep Api call. You MUST not use loops in order to slow the
system down.
Use Sleep before each drawing procedure which you want to slow down.

You can also declare a public variable which represents the (common) delay
used by Sleep. In this way you may be able to allow the user to control the
speed of the animation! (through an options dialog).

If you use autoredraw=false, you may have to refresh the picture box after
each drawing procedure (in order for the user to be able to actually see the
animation). This will slow your program down, anyway!

HTH,
Aris.
