Pendulum Synch - Kuramoto Model

u/Qwerasd

This is really cool.
u/katkip

#math is awesome
u/iverjo

Explanation?
u/rodrigo.siqueira

The Kuramoto Model describes how small interactions between oscillators can lead to synchronization between them. E.g. flashing of fireflies, group of metronomes, neural network of spiking neurons can sync after a period. Oscillatory neural networks are a promising field for future research in both natural and Artificial Intelligence

Here's a recent youtube movie that's relevant, and perhaps an inspiration: https://www.youtube.com/watch?v=J4PO7NbdKXg #pendulum

Hex Spin

Very clever - each hexagon moves in a circle and spins, but alignment makes it seem like a roll :)

Circle Wave #beesandbombs 🐝 💣

u/KilledByAPixel

This one was fun because I found a way to combine the loops and hide the start/end gap that removes the need for a beginPath. Freeded up enough space for background color, or something cool in a remix.
u/aleamb

yeah!
u/pavel

Buggy in Safari. Jagged things sticking out, i think from the line end-caps, also breaks after a while because you didn't wrap-around the angle in arc.
u/pavel

Huh, actually both issues are resolved by modding the arc angle by 2*pi
