Animated Hypocycloid Charts

With a few simple macros, you can creating some interesting animation effects in charts. For example, I created a workbook that displays an infinite number of dazzling animated charts. The workbook is set up with a simple user interface that makes it very easy to generate a new chart or save the parameters for charts that you like. Turn animation on or off with the click of a button.
The chart displays what's known as a hypocycloid curve -- the path formed by a point on a circle that rolls inside of another circle. This, as you may recall from your childhood, is the same technique used in Hasbro's popular Spirograph toy.
The workbook is not protected, so you can view the formulas and VBA macros that are used.
Excel has a long history, and it continues to evolve and change. Consequently, the tips provided here do not necessarily apply to all versions of Excel.
In particular, the user interface for Excel 2007 (and later), is vastly different from its predecessors. Therefore, the menu commands listed in older tips, will not correspond to the Excel 2007 (and later) user interface.
