PixelTwister can make a picture or movie look like a black-and-white pencil sketch, colored pencil drawing, scratchboard drawing, or painting.

- Open a picture or movie, manipulate the settings (or click the Randomize button and see what happens) until you get something you like.

- If you're making a movie, check the Mutate boxes to have the various parameters evolve as the movie is generated.
