“Peur et dégout à Limoilou” is a generative artwork composed of a grid of pixels. The color of each pixel is dynamically influenced by an algorithm called "Perlin Noise," giving rise to a captivating visual composition. The algorithm assigns a value to each pixel, and this value corresponds to an index, which is associated with a color from a carefully selected set of color palettes.
What makes this artwork particularly intriguing is its propensity to trigger pareidolia, a psychological phenomenon where familiar shapes or patterns, such as faces, are perceived in random or ambiguous stimuli, such as clouds, stains, or abstract patterns. It's essentially our brain's attempt to make sense of indeterminate stimuli by interpreting them as something familiar.
Although the algorithm operates on random noise, the human brain naturally seeks familiar patterns and interprets them as faces or recognizable forms. This enchanting phenomenon adds an element of surprise and wonder to the visual experience, as viewers may discover imaginary faces emerging from the subtleties of the pixel grid.
