MarsEdit Post-Mortem
In an alternate universe, MarsEdit is an outliner instead of a weblog editor—and its name is MarsLiner. It has the exact same icon MarsEdit has.
When I first asked Bryan to make a Mars-with-spaceship icon—way back in early 2003 (I think—could have been 2002) it was for an application named MarsLiner. The idea was to do an outliner that could fill in for MORE.
