My obligation-quotient has been on the rise this week, and so I offer something a bit more on the fly. While most of my work is digital, that usually involves a graphics pad and several Adobe products. This week, though, I offer a little cartoon for the theme developed on the iPhone with iPhone apps. Consider it the digital equivalent of a field sketch, awaiting opportunity to get back to the better materials in the studio. But really, that's not going to happen before Thursday.
