The signs movements of fluids are found in all that we are. The heart is our source of energy , the blood is transmitted to the parts of our body, as in nature, the water is distributed through the whole system. With this concept Roberto Tres begins a study of the traces left water and liquid matter. This work explores Roberto Tres investigating and stopping the movement of fluids, contrasting the different densities of them visually to highlight those particular inherent within matter. On the surface in Fluid Forms is impressed the flow of matter, blocking an instant and making objective a fraction of time. Initially using as a support paper sizes "Imprinting series" similar to a small impression on photo paper then increasing the size of large surface materials such as aluminum or canvas prepared. The Fluid Forms are works that are dealing with the fluid matter are part of the artistic way of Roberto Tres this works can be interpreted as two-dimensional sculptures in which the texture is identified by color in all its forms and compositions.

The world around us is made ​​of a substance visible and invisible this is the Fluid. The Fluid can be transformed by the liquid material to solid matter, it is located in several forms on nature. If we think of the process of cooling water is the same at other liquid forms for example "when magma cools it begins to form solid mineral phases " then becomes solidified in Vulcanic Rock. This process sometimes we can recognize and find it in material already formed solid matter. The Marble presents multiple layers which were originally fluid. Another factor, which it affects to determines the characteristic of the solid material is the time that marks the turn of events. Roberto Tres used material to detect a difference between the void and the time, almost impossible to perceive the passage of time all of the movement seems to be motionless. To emphasize the idea of the void. Tres use this material that jailed the idea of the movement inside it, suggesting the terms and parameters required in order to perceive the void.
