I saw a poster on TIGSource talk about manually cutting up sprite sheets, so I've dusted off a project from 2007 to solve it. Just load up a sprite sheet, select the background color, and export the results into a directory. It's got a few extra features useful for what I originally wanted it for, too.

You ever want a Lauchy command to control MediaMonkey? Well now you got it. Just download the attached zip, and extract it somewhere Launchy can see .lnk files (like the default Utilities folder, e.g.). The same files work for Winamp, just change the names to something more appropriate.
