If this long workshop hasn't left you feeling threadbare, expand your skills with the following activities:

  • If you are comfortable with HTML, create your own home page that includes the Revolve applet and six of your own favorite websites. Use the applet along with other graphics and text on the page.
  • Add a button to the FindPrimes app that can stop the thread while the sequence of prime numbers is still being calculated.
