    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Underwater lava cave #perspective

u/tomxor

I keep switching perception between cave and mountain top, it gets stuck on mountain top... i can't control it 😳
u/sigveseb

I don't see mountain top 🤔 how?!
u/tomxor

funny, i can't see anything else now... it;s like looking down from above a mountain peak. Maybe imagine you are looking down from a circling helicopter.
u/rodrigo.siqueira

This #illusion is called "bistable perception". When I posted it was looking like a cave, now it seems to keep changing between mountain top and cave. I prefer a cave.
u/sigveseb

yes, I see it now!
u/rodrigo.siqueira

#tunnel
u/joeytwiddle

To see the mountaintop, maybe look at the blue and imagine it is the floor or the sea, far away.

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
u/lionleaf

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