You may have had a shot at creating a Quicksilver interface. (If you haven’t, see the tutorial). While it’s good fun to play with changing the colors and positions of the controls, there is a whole lot of really clever code in Quicksilver that lets you go beyond that and play with some weird and wacky effects on any window.

AppZapper, the uninstaller Apple forget, is a great way to remove applications along with any garbage files they may have left on your system in the form of preferences, caches, and application support. Using Quicksilver, removing an application with AppZapper is as easy as a simple hotkey or trigger.

It’s finished. The real craze and controversy over Disco’s smoke is over. Jonathan Wight was the first to write up an article on integrating the smoke effects into a third party Cocoa application. Times have changed, and the smoke framework bundled with the more recent versions of the application no longer produce the desired results by using the same code.

So how do you get any Cocoa application to start smoking? Austin Sarner was kind enough to reveal the usage and implementation of the changes to the Disco framework which allow a wider variety of Macs to experience the entertaining effect.
