Joystiq - You know how they say that water is the essence of life? In Vessel, water takes it one more step: It literally becomes life. Inventor Arkwright has invented what he calls Fluros, little creatures that attract any liquid around them and build them into a body. They're pretty great for doing work around his factory, especially because of their seemingly bottomless desire to step on buttons. Handily, Arkwright's entire factory seems to run on those little buttons.
