Interesting, I’ll have to check it out. I’ve been passively wanting to leave brave on iOS for some time now. Thank you!

I got inspired and made a similar effect is desmos

f(theta, t) = 0.1 max(cos(theta + t), 0)^2 sin(8 theta)

r = 1 + f(theta, t)
r = 1 - f(theta, t)
where: 0 <= theta <= 2 pi

t = 0
where: 0 <= t < 2 pi

It’s not quite right though, the sin(8 theta) part needs to phase shift, but basing it off of t messes up the perfect loop.

At that point I would reach for code, which also lets you save the animation. Using something like p5.js (editor.p5js.org) you can easily draw graphics and save each frame as its own image

this might not be what you meant, but the word “tar” made me think of tar.gz. Don’t most sites compress the HTTP response body with gzip? What’s to stop you from sending a zip bomb over the network?
