The Photoshop Channels Book

This is one of those things that just makes you smileif you're chatting with someone and you minimize their chat window to the Dock (maybe they're taking a break for a moment, for a snack, etc.), their buddy photo shows up in your Dock as a Dock icon (as shown here, where my good friend and Creative Director Felix Nelson is killing some time in my Dock). When your chat buddy comes back and sends you a message, a tiny iChat AV icon slowly blinks on and off to get your attention.
