🐱 2D Anosov Cat Map (2D)

Interactive 2D Canvas simulation of Arnold's cat map, the canonical Anosov diffeomorphism. Iterate a real linear map (x,y) → (x+py, qx+(pq+1)y) mod 1 on a pixel grid and watch the image mix into chaos and recur.

⚙ Under the hood

Interactive 2D Canvas simulation of Arnold's cat map, the canonical Anosov diffeomorphism. Step through real linear-map iterations on a pixel grid, watch the image scramble into chaos, and see it recur to its original state after a finite period. Adjust the matrix coefficients and grid resolution to explore hyperbolic mixing live.
