Piece for the genuary32nd party.
Enhanced version from my genuary 17 piece (A grid inside a grid inside a grid).

This is a random walker that creates grids with its walking paths. He walks with 3 different step sizes (1/10, 1/20, 1/40 of the screen size) making this way a kind of irregular grid inside a grid, inside another grid.

It is possible to get a walker grid with 3 different lengths (800,1200, 2000 steps), in mono-color or multi-color.
