Cartoons, Comic Strips, and User Interfaces

Cartoons and comic strips are interesting forms of communication. Cartoons are simple, yet expressive. One of the philosophies of Hotdog LINUX is for the user interface to be reminiscent of a cartoon or comic.

This stands in opposition to flat design. I'm not sure if there is an underlying philosophy to flat design, other than "let's throw out what works well and try something else." Sounds like a great idea.
