For anyone who's interested - I recently worked with Bill to take his original T-SQL code and translate it into a C# Silverlight web application with a GUI that displays the robot's moves so you can actually see it working.

You can find the application by clicking the following link:

You'll need to have Silverlight installed for it to run.

It may still need a minor bug or two worked out, but it's still a cool, functional, GUI representation of the T-SQL algorithm.
