Use the code inside this project to make your own Op Art and add it to the Op Art Studio. The Scratch Cat "mask" code is inside the project. You change the code that draws the patterns inside and outside the masked area. You could use vertical lines for Scratch Cat and horizontal lines outside, you could colour Scratch Cat orange and black, you could use diagonal lines, circles or umpteen other patterns.
