[Icehouse] (revisit to---) Rotationary Rules - is this it?

[Joseph Pate]

Now I'm confused, but admittedly I'm just lurking...

I think the rule for the Large-original should be spelled out, rather
than some implied recursion to save rules text.

In my mind, "once more" is ambiguous; does it mean:

1)  Rotate the 1CR piece an additional 90deg?
2)  Rotate the 2CR piece an additional 90deg?
3)  Rotate the 3CR piece 90deg?

I think #3 is intended, and that makes sense from a CRs-to-pips standpoint,
but it could be clearer.  Basically you need to propagate the rotation
through X successive pieces (X = #pips on the selected piece) -- unless
at any point in the chain, the just-rotated piece fails to point to 
another piece.

Is this accurate?  I know you can't just change the text to what I've 
said, because 'propagate the rotation' is not in itself well-defined
either, but I think it serves well enough to communicate my point (or 
doesn't it?)

I can see I'm going to have to try Rotationary myself, now that I've 
been sucked in  ;-)
