Piece aspects
In the absence of any better suggestions uit looks like I'll have to go ahead with my own ones. I have tentatively devised terming a rotating rectlinear piece Dual-inclusive if it includes 45° turns - with rules about how moves are affected, and Pivoted if it can turn no more than 45° either (or on a cubic board, any) way from its array orientation.
So if I read no better ideas by the time I go online on Sunday morning (about 48 hours from this posting) I'll post Starboard/Larboard Duals on Man and Beast 12, Dual-inclusive/Pivoted rotating pieces on Man and Beast 15, and Spearsman pieces on Man and Beast 16. In the meantime I'll add to Man and Beast 09 and 20 a few additional alternators which I have been mulling over.
