A simulation of a double pendulum, where the balls have equal mass and the (massless) sticks connecting them is 0.1 meters long. The simulation is made in MATLAB, exported frame by frame (4000 frames) and converted to a 80 seconds long video (50 fps, real-time) using ffmpeg.

This was a bonus task regarding differential equations and numerical methods in our "Continued mathematical analysis" at Chalmers University of Technology.
