Fumo has since been updated.
With so many people asking, I just can’t procrastinate any longer. You win. Here it is.
It’s most definitely not the finished thing yet. Yes, I have been taking a while. No, there is nothing you can do about it (short of asking for the source and developing it, which you may do by sending me a polite email). Continue Reading Fumo still smokes - has non-smoking evil twin

This version’s not publicly available yet. Austin & Co. (developers of the application that uses this effect) need to be contacted, and I need to have an option to turn the smoke on / off. It cools down automatically when the interface is hidden, but I’m sure not everyone likes passive smoking.
Doesn’t it look fantastic?

This is mainly for developers, but if you’re a Quicksilver user and want to get a taste of the upcoming Fumo interface, feel free to tune in.
Nicholas Jitkoff, aka Alcor, the developer of Quicksilver has been extremely generous in providing assistance and code. A developer by the name of “ytrewq1″ has also been very gracious. Sincere appreciation to both of them.
Well, let’s take a look at how Fumo is shaping up. I’ve added a sliding transition for when it’s activated so it shoots down from the top of the screen. I’ve also made the contentView of the window transparent, and added a custom view to which the rendering of the background is done. Trust me, it’s easier that way.

The transition for the window exiting (by sliding out) is very crude and you’ll notice that I’ve had to use the “reallyOrderOut:” method on the window since orderOut makes it fade out, and it looks weird if the window slides out of the screen, then reappears and fades.
Final thing, (actually the first real thing I did) was the subclassing of the “activateInTextMode:” method. Try activating the interface in text mode (you’ll need to have a trigger for Command Window in Text Mode). Hopefully you get a very nice warping effect.
Next on the agenda is changing the background and text color of the actual searching views. Take a shot at it if you like. Here’s the source code:
