I moved the Diagram into the article, with a few modifications. Besides the coloring, I used a different method for implementing the 1st-rank double push: a morph prevents Pawns from moving into the enemy board half, but the single steps are then exempted from that by writing a prime behind the corresponding Betza atoms. This gives a more palatable move description in the piece table than the method of 'sensing' the board edge.
Note that the chess font in the 'winter' directory here is actually known as 'Companion' or 'Good Companion'; I now uploaded the SVG for that font to CVP so it can be used by fen2.php (t=companion in the query string), and made a few 100x100 PNG images of it (and some knight compounds), which I put in /graphics.dir/companionPNG/ .
As to the variant itself: it might be too easy to build an impenetrable wall preventing the opponent from reachin your King or back rank.
