Concrete

There are 3 main types of concrete. Concrete nodes, when they touch water, turn into their corresponding liquid form. These liquids, over time, if exposed to air, turn into their concrete "product". Concretes have a pliant stage between the liquid stage and product stage where they are able to be etched with a stylus into many different patterns.
