Amazing Desktop
Lifehackers has a writeup on how to Roll Your Own Lightning at Sunset Desktop. That is one impressive-looking desktop. AutoHotkey sounds as though it might be useful - I’ll have to give it a shot sometime.
I’ve started using Launchy recently and I really like it. So far I’ve just been using its basic functionality but I’m looking forward to digging deeper and finding more uses for it.
Samurize looks interesting but I don’t look at my desktop that much. Maybe I’ll give it a try.
