A group of Australian anatomy students were treated to a real life male anatomy model last month, care of handsome young Zac O'Brien and a team of artists. O'Brien sat for 18 hours for the project, having his well defined body further defined with the aid of markers and smudge-free body paint, ultimately coming out looking like a slightly scary, three-dimensional version of a text book anatomy illustration, bloody muscles and all. Kind of cool, and also, a little bit erotic for the ladies and gays, until, at least, the full paint goes on. [The Age via Buzzfeed]
