Challenge: Change the program so that instead of typing in your choice, 3 sprites appear (one rock, one scissors, and one paper) and you click on the sprite to make your choice. Extra challenge: Add in the possibilities of Lizard and Spock. From Wikipedia: One popular five-weapon expansion is "rock paper scissors Spock lizard", invented by Sam Kass and Karen Bryla,[90] which adds "Spock" and "lizard" to the standard three choices. "Spock" is signified with the Star Trek Vulcan salute, while "lizard" is shown by forming the hand into a sock-puppet-like mouth. Spock smashes scissors and vaporizes rock; he is poisoned by lizard and disproved by paper. Lizard poisons Spock and eats paper; it is crushed by rock and decapitated by scissors.
