Spanish software engineer Inigo Quilez launches Human Shader, a web-project that aims to crowd-source the creation of “the first-ever brain-powered mathematical image.” Participants are invited to claim a random pixel, hand-compute its RGB values, and submit the results along with a photo of their pen-and-paper calculations. As a veteran demoscener, Quilez is no stranger to computer graphics wizardry: he’s behind the Shadertoy platform, the Quill VR painting tool, and Pixar’s Wonder Moss generator.
