I wanted to continue the same "trick" theme from 2015, since this is
still the TRICK contest.  The shell game entry from 2015 won but the
trick art samples didn't, so I thought I would try that again.

At least that's how I remembered it.  It seemed that I spent a couple
of weeks on this, wrote a maze generator that made use of some trick
art perspectives, and then added a solver to give it extra flair.

And then I submitted the whole thing and forgot about it without
writing more documentation.  Oh well.  It did get an honorable
mention.
