Al,

I put up an application using the "intersection" function which does 
something quite similar to this on my web site some time ago. It was 
a response to a question on the list about colliding polygons. You 
can drag or propel one polygon to/at another. They beep or bounce off 
one another when any line of one polygon intersect any  line of the 
other.
