Hyperbolic Turtle Graphics is a python tool to explore hyperbolic geometry in the Poincaré disk model. It is based on the turtle standard library module. Basically one interacts with a "turtle" as in the Logo programming language but the instructions of moving forward or turning are carried out with respect to the Poincaré metric.
