FUN &  GAMES:
Mystery of Time and Space
Mystery of Time and Space  a.k.a. Black Hole for Time

It's one of those puzzles where you find yourself in a locked room, and have to figure your way out.  Only to find yourself in yet another room.   How many rooms?  Play and find out!  Click on random objects to find helpful objects.

It's one of the better games of this genre.
Make-A-Flake
This is a fun little program that lets you create your own snowflakes.

Happy snipping!
Critters
This is a fun game.  It's deceptively simple, but there is really tremendous strategy involved.  You can buy different weapons to try to kill the critters, with each level bringing tougher (or faster or susceptible to certain weapon types only) critters.
