Element Sketchpad

Element Sketchpad is a purely Euclidean interactive notebook with coloring, animation, and sound as first-class citizens alongside compass and straightedge constructions. Create animations, play games with your friends, or work through all of mathematics starting with Euclid’s Proposition 1.1 … in a world with no numbers and no coordinates and no words. Where touchpad users, AI agents, and Element Scheme scripts emitting the Construction Calculus all interact as purely geometric entities.
