I would like to run this concept as part of the Chess of Tomorrow project. 
Someone in discussing the future of chess, brought up Calvinball.  The
posted a link to one set of rules:
http://www.bartel.org/calvinball/

There is one permanent rule they have for Calvinball on that page.  That
rule is this one: You may not play the Calvinball the same way twice.  

So the basic framework for the ultimate chess variant would be, can you
have a chess playing framework that would enable a person to NEVER play
chess the same way twice (by the exact same set of rules).  A softer
version of this challenge would be that a person would play both side
(black and white) each once, before moving on to a set of rules.  A
Calvinball tournament would consist of this rules though.

Please feel free to discuss this hear, or if you want it to add to the
Chess of Tomorrow project, post in here:
