%N Fibonacci word fractal in an n X n grid, starting downwards from the top-left corner, listed antidiagonally.

%C The n-th iteration of this curve ends at the n-th Fibonacci number.

%C As this is not a space-filling curve, not all points on the grid are reached by the curve; these points are given the value 0.
