Ex-OpenAI designer details evolution of random gradient generation techniques
A designer who worked alongside OpenAI's Ben Barry recounts building multiple algorithms for generating random gradient art, starting from Barry's 2017 four-corner color interpolation. The author later developed heightmap-based gradients using smoothed Perlin noise combined with randomized color scales, and separately built a lightweight layered radial gradient system that powered OpenAI's homepage in 2019 using an 85-byte image.
