Make your own op-art style artwork. Save it or e-mail it for printing.
OpArt Designer — description
If you like op-art (for example, Victor Vasarely's art) you will love this app. Design your own artwork, give it a title, save it, and/or send it to your computer for printing - it's free!. Browse all saved pieces, select and restore one, and continue to work on it. Share it from the Gallery to Facebook, Twitter or whatever. With version 2 you get a new color saver, and you can choose resolution for saved images up to 16 megapixels - enough for printing a poster.
