The Synesthetic Cube

George Sanen is a synesthesia artist who creates these Synesthetic Cubes. Different names are portrayed as different colors in his mind, so he makes these cubes for families or other groups of people that include the colors of the names they gave him.

"The Synesthetic Cube is the result of a series of ideas and motivations to blend a geometric shape seen through Synesthesia while utilizing the colors perceived by correlation to personal names.
Thus the formation of a multi-colored series of bands or other shapes that represent the liaison of a specific group of people, family and friends. In other words, a form of art that has a significantly higher meaning to the observer other than the mere pleasure of observing art for its own beauty.
Having each color representing the name of a person the placement of the color on the cube is done completely at random, or by personal selection or preference."
