It's a simple formula I recently used to figure out a custom logo to give the comics community. I had no idea what to doodle and thought Bill Watterson deserves better than a modest alien homage. This is something I've been doing for redditor-created communities that have taken off.
Fortunately, the comics community had plenty of ideas. I ultimately went with a comic panel look suggested by irrelevantnotch.
Oh yes, that's "fightin' Splashy" in there.
