[Chicago] Communicating across layers in a webapp

[Randy Baxley]

I am talking about Visual CTA Chicago's front end and back end.  I only try
to code on it because I have been unable to Tom Sawyer anyone else into
doing it.

It really is fun though and a real kick when in a tall building where you
can see the trains and buses doing what your code says they are doing.
