A couple of off-the-cuff ideas:
Rotation:
A rotation of a piece would count as a move (a la 3M's Ploy), but perhaps
should be limited in such a way as rooks remain rooks and bishops remain
bishops, etc.
Size:
Pieces could start at eight squares, and change size as a move. That might
be interesting, because a shorter piece would have less influence but might
be able to slip through places otherwise blocked.
