Windows users are familiar with a number of utilities for setting system preferences, but Mac users have not had as many options. GeekTool is a solid attempt to remedy that situation by bringing an alternate way to handle many Mac system settings. The app installs quickly and opens to a simple interface allowing you to create "geeklets," which accomplish specific tasks. You drag the geeklet icon to your desktop, which then opens a dialog allowing you to customize the behavior of the geeklet. Options in the dialog vary depending on the type of geeklet you are creating.
