I have shaped up the article a bit (margins around the image, and a typo), changed the explanation about the irreversibility diagram such that the Griffon did not come from a square where it could capture the King (b1), and added a link to a Checkmating Applet that can handle bent riders. (Which I uploaded for the purpose.)
For now that Applet is hard-coded for doing a Griffon, as I took out all piece-selection buttons to make it look to the EGT page we already have. I am not sure whether we will need it for other pieces. The Ostrich (A-then-R) can checkmate, but I don't think we have a Piececlopedia page for that. The Applet doesn't do lame pieces, so it cannot handle the Hippogrif. It might be able to do the jumping version (which on a near-empty board would be nearly the same). It can also do the Ski-Rook (which is a sort of degenerate bent slider, D-then-R). But we also don't have a Piececlopedia page for ski pieces.
