Rouge 106 - Bleu 132, 2003
Semi-transparent surface, vibrating colours

The artist has positioned blue and red light at the upper edge of a semi-transparent, walk-in box. The light flickers at a rapid 7.5 Hertz, a frequency that corresponds with human brain activity, causing the primary colours to create a glaring white that is unstable and barely visible to the human eye.

Duration: 10:50 minutes
Here the artist works with decelerated illumination of a light bulb and a neon tube, making visible the near-imperceptible light that is the precondition of visual experience.
