Hello! Welcome!
Here's a page of some stuff that might be useful or interesting. Probably not though... Being interesting and useful is not one of my strong points.
I would write more about myself here, but then what would I write on the "About" page?
The graph to the right there is a plot inspired by this video. What I did was solve for the position of the pen, given the positions of the pendulums and ran a parametric plot for the pendulums moving wrt time for small oscillations and with friction. To further that, I gave them some funny modes of oscillation.
Try refreshing the picture (protip: press r), it should be different enough each time. It's not purely random, though, because I kept getting some bad results if I just let it do its own thing, so you will see some similar types popping up.
The code is available in the programming section.
