Great!  Thanks.

I don't know if this is your style or if it fits your application, but
instead of writing out a long list of points, I sometimes find it
easier to use a for loop.

I can declare a metapost array for holding points or paths, and then
initialize it using a for loop and some simple math.  It makes the
code much easier to read, understand, and maintain.
