A 19 year old artist, Chooo-San (yup, that’s 3 o’s and 1 hyphen), attending school in Japan paints right on peoples’ skin. No Photoshop, just acrylic paints. Dude said “I was a little sick of everyone making pictures with their computers and wanted to see how far I can go without those technologies such as Photoshop. My works are all done with acrylic paints. They are all painted on skin directly and I don’t use computers or anything to change the picture afterwards.”
My guess: he was just fishing for a way to get girls to take their shirts off. Well played Chooo-Chooo, well played.
