Tool for Drawing Pi-Shells size change when they experience velocity

Here is a tool which draws Pi-Shells which are under the influence of velocity.  It uses HTML 5 which is built into the latest modern browsers.  Tested on Opera/Firefox/Chrome.

It shows the Observer 1.0 Area loss due to velocity
The size of the new Pi-Shell with the area loss.
It uses the Lorentz-Fitzgerald Transformation

Note:

I will add the HTML to an Appendix document later.  Alternatively, just open the doc and view the source.
