Monkey Lander is a monkey-driven rocket-powered Flash-based version of the venerable Lunar Lander game. You can find a version of the old Lunar Lander as a Java applet too. But Monkey Lander has more character, and includes fruit and goodies to gather for points before trying to land. A simple, fun diversion, and Totebo's site has quite a few more when you've killed enough monkeys.
