A series of webcomics that all take place in the same universe, generally about animals creating society with the power of both art and 'Art', which is a form of metaphysical martial arts. My personal favorite comic here is 10%+.

This takes place in the 1900s during prohibition, and it has the most beautiful art I have ever seen a webcomic have. Lackadaisy revolves around a failing speak-easy, and the lives of the people who run it. It is extremely well researched, to an insane degree, and there is currently an animated short in the works. Also they're all anthropomorphic cats.
