quilt geometry?

quilt geometry.

An interface that looks like quilt geometry, that's what I'm going for. It's basically simple, but intriguing and fun to explore--a good control interface if you ask me.

I am, for the moment, not thinking about the whole of the game; I need something solid to latch on to.

for the sake of having something to write about, I'll propose the already-discarded specifics for an idea for this interface:

The pattern is made up of four rows and four columns (see quilt examples), the internal two-shaded squares would make up the controls. these squares could be rotated, added or taken away from the grid, and switched with adjacent squares (including diagonals). Each square of the grid (not the two-shaded pieces, but the underlying grid squares) would represent a subject, or line of music, which could be manipulated (perhaps in the way a subject is manipulated in a fugue) based on the position and orientation of the imposed two-shaded piece.

Grid squares occupied by a two-shaded piece would be heard, and altered accordingly. Changes made in the pattern would be heard in the next measure.

This idea is far too basic I think. I'm trying think of a way to complicate the process in an "elegant" sort of way.
