This MCG will pixelize a closed spline, ie. your path will be populated with 'blocks' in a grid formation. Custom objects can be used like a hexagon, sphere..etc. You can progressively populate your path in either direction, works best on CLOSED paths, for open paths, please use single spline path.
Please note: First pic shows ver 1.00 but it really is ver 1.02, as can be seen in last pic.
