I definetely don’t know what good art is but I know what I like and I like Murakami’s work. I is bright, full of life and has a light hearted-ness to it (even some of the stuff that is twisted and methed out). His cartoons that he’s done have been pretty cool as well. He’s worked with Louis Vuitton and Kanye over the years (and quite a few others) but for the Summer Solstice he was commissioned to “redesign” the Google logo. Follow the links and get a little more insight on him and his work.
