Scribble Flinger (version 2) is a font that can be as dirty or as refined as you want.
Normally, Scribble Flinger is a blend of gracious style and scribbled haste, perfect for something that needs to be elegant in an off-hand way. Turn on the OpenType "contextual alternate" option, however, and the font goes grunge: stains, smudges, and ink spatters. It's your choice - this versatile font can do whatever you want!
Look for the upcoming iOS game by the same name.
