TAKAHASHI Hoshino ‘Prototype for Expressing the Irrational Numbers’


Twelve 32 x 32 dot LED panels are arranged in a circle. The single LEDs are switched on one after another, whereas there are some that do not light up, others that light up continuously, and yet others that blink. According to their different blinking speed, the LEDs display numbers from 0 to 9. At the same time, numbers from 0 to 9 are also projected in the form of different colored lights from a projector.

This installation is a synesthesia-based attempt to display the irrational number “Pi” according to the “relationship between numbers and colors” that is generated through the artist’s own synesthetic experience. An irrational number is a number that cannot be expressed as a fraction, which means an endless row of irregular decimals. TAKAHASHI uses a circular arrangement of LED panels to express “Pi” as an irrational number that cannot be displayed in its entirety. Synesthesia is a perceptual phenomenon in which stimulation of one sensory organ triggers the involuntary response of another. It occurs inside the brain through the interaction of multiple senses that are supposedly not connected. Types of synesthesia vary from one person to another, such as seeing letters in different colors, perceiving sounds or flavors as shapes, or associating pain with colors. It is said that this phenomenon often disappears during childhood.

The sequences expressed through lights and colors represent at once sceneries that only appear via the artist’s own eyes and brain. The work was made with the intention to capture the perception of beauty in numbers, and the awareness that it may change at some point.
