Here's a nifty little OS X program that was mentioned on Forwarding Address: OS X. It's called Quicksilver. I have many friends who love a program called LaunchBar for launching things, but for some reason it never really clicked with me. But there's something I can't put my finger on about Quicksilver that I like. It's got some really slick features in there. Even if you are a LaunchBar user you should check it out, it's free (and still beta, so be warned).

I also found a handy tutorial for Quicksilver while reading through the forums.
