The Ecartis Web GUI is a simple but useful Web GUI written in PHP for the Ecartis mailing list software. The goal is to allow non-technical users to administer their own mailing lists, while leaving configuration options to be set by the sysadmin in accordance with site policies. It has the ability to subscribe/unsubscribe people to/from a mailing list, and also to list the current subscribers for a given list.
The College Radio Database is Web-based software for radio stations. It allows you to track large collections of CDs by unique ID, assign status, do basic searches, and more. It also tracks airplay, allowing easy entry of spins from the CD database, as well as entry of DJ-supplied music. Top XX overall/by genre charts can be generated between 2 dates, and you can check up on DJ attendance, number of spins versus station spins, and more. It also includes the ability to maintain DJ schedules in table form for multiple semesters. This software has been in use at WMBC Radio and evolving since the year 2000.

The "lab" had two IBM compatibles and 20 or so TI green screens (half the typing class was taught in there; the other half used typewriters). If I hadn't managed to nab one of the PCs, I'd "help" someone who was using one of them to finish, then get the DOS disks. All in the name of Scorched Earth (you know, the Mother of All Games).
xscorch is even better than the original (which is still, amazingly, shareware); they've added many cool things, such as solar cells which gradually recharge your tank, while sticking very close to the original look and feel.
Another cool, relatively simple game is Liquid War, which (if I'm not mistaken) is an original concept:
