Use the Scratch Cat Outline costume inside this project to make your own Op Art and add it to the Op Art Studio. Add your own patterns with rectangles, lines, ellipses or other shapes to the outline costume. They should overlap a bit. Then convert the costume to bitmap and fill areas with colour to make your own Scratch Cat Op Art picture. There are also outlines for other Scratch Characters inside this project. You can backpack the costumes or remix this project.
