If you use a MacBook Pro or a Powerbook with a backlit keyboard, this is for you. Labtick is a cool free app that allows you to adjust the backlight level on the laptop (and overrule the sometimes erratic ambient light settings that the laptop chooses.) (10.4 and 10.5 friendly)
Mactracker is a great program. It is a list of every Mac ever made and the specs to go along with them. When I am trying to help someone figure out how much RAM they can put in the PowerMac 9500, it comes in real handy... it is also fun to look at the specs of the first Macs compared to where we are now. They also have added Apple iPods, keyboards, displays and just about every other Apple branded item to the database. (10.4 and 10.5 friendly)
Monolingual is a free utility that will remove all of the other languages installed on your computer. If you are running low on memory, this can free up some space. A lot of progams install a whole boatload of languages even though most of us never get away from English on our Macs. I would suggest backing up your machine before running this... just in case.This last one is a program that I stumbled across and it looks like it could be fun to play with. It is called MacOSaiX and does what the name sounds like... makes mosaics out of your photos. (It is supposed to be 10.4 and 10.5 friendly)
