Rocket Matter Icon in Mac OS X Dock

Did you know you can put the Rocket Matter rocket ship logo in your Mac OS X dock and launch it directly?

Thanks to Tim Evans, who can be followed on Twitter at @timothyevans, for sharing this image of his desktop.  Using Fluid and a graphic, he created an icon for RM.  You can see his screenshot here:  http://twitpic.com/udzg.  For your own logo, you can download the logo in this post and ask Tim how he did this!
