I did a complete write-up on XBetza recently, and submitted it to CVP as an article. It also contains an updated copy of the 'Betza sandbox'. But it isn't approved by the editors yet.

This is demo featuring a Joker. I see now that the pure I atom describes a bi-directional Joker, which imitates both the piece and its 180-degrees flipped version. This was not my original intention. But perhaps it is just as well, as without directional modifiers Betza atoms always move in all directions, and it would be ugly if I was an exception. So I changed the definition of the Joker in the diagram above to fI, so that it only imitates the Pawn moves as if they were Pawns of its own color.
