Antimateria (antimatter) is the intangible substance through which it's possible to demonstrate the fundamental symmetry: for each particle correspond an anti-particle. When the two essences are close and in the same environment, the anti-particles disappear for annihilation, they are ephemeral.

An emotion represents an instant of antimateria, an ephemeral moment able to stress a person and prime a reaction. The visual art is a contemporary way of ephemeral expression in which the light gives life and animates the space; it is able to modify the perception untouchably becoming the actor that prime that reaction.
