FUN is the underlying concept behind this poster.
The only scientific proof of the sensation of FUN comes from the registration of Brain Waves, more specifically the Alpha brain waves that are generated by the human brain when a person is in a state of relaxation. Alpha brain waves are described as sublime, flying, floating, lightness feeling with no time and space limitation.
The white lined waves in this poster are the graphical representation of the Alpha brain waves that have an equivocal nature, as they can also be interpreted as sea waves in the blue background.
