Drag the SpirographX.saver to the Screen Savers folder in your Libary folder. The library folder is located in your Home folder ("~/Library/Screen Savers"). Once you've done that, open system preferences and click "screen effects".

Setting the Interval slider changes the amount of time between transitions. If you feel like your going into a seizure, you probably want to set this lower.
Setting the detail slider changes the number of line segments drawn to make the image. If you want prettier pictures, or if the screensaver runs too fast, set this higher. If the screensaver runs too slow, set this lower.
