Lunar Lander...
John Donohue did a wonderful job of Java programming and we can't thank him enough for making it available. Your browser will have to be able to run Java programs in order for you to play Lunar Lander.
Instructions:
The instructions for Lunar Lander couldn't be easier. Use the space bar for the landing
thruster and the left/right arrow keys to spin the Lander. Try to land on the blue landing
pads. Land successfully and you get half your fuel back. Change the gravity to make it
harder.
