            // everything from this point on is just drawing junk into the BitmapData object
            var p:Point = new Point (0, 0);
            for (var y = 0; y < canvasSize; y++)

                    if (p.x % size == p.y % size)
                        bd.setPixel(p.x, p.y, 0x00FF00);
                }
