A hyperbolic string art portrait of Henri Poincaré. In the Poincaré disk model of 2-dimensional hyperbolic geometry, each straight lines is a circular arc that is orthogonal to the boundary of the disk. In this portrait, there are 387 such lines (and 120 points on the boundary). https://t.co/cQ7c28XIrl
