Phase space of double pendulum

The chaotic behaviour of double pendulum is very interesting. If we slightly change the initial angle, we will end up in completely different phase space. I decided to see how its changing, so I put the tow initial angles in nested loop and incremented in steps of 5 degree, from 0 to 90 degree.
The result is the colourful display of phase space. As you see in the video, the one in the top left is the time graph and bottom right is the phase space. It's a python script with gnuplot.
