pattern notation

I've come up with a weird pattern notation scheme that can be used to record played patterns in the game. It's a bit hard to explain in words, so I'll make a diagram:


The three different shapes are labeled "sharp" "flat" and "natural" (referencing music notation). The four sides of each shape are labeled 1, 2, A, B going clockwise. The position of the bead determines where the starting point is, as pictured in the diagram.
