Rotating Double Donuts #torus #donut 🍩🍩

u/TGY

I don't think you need "var" there. It works fine without it :)
u/New_Core

nice, and its 5 FPS faster with the "var" then without on my old machine.

Nice! Double donuts everywhere!
u/pavel

Not a fan of the obfuscated code. Looks nice to people who don't care to understand it but hurts your fellow coders that want to play around with it, which is a big part of Dwitter for me.

u/rodrigo.siqueira

I posted a cleaner version (remix). I usually avoid obfuscated code, but in this case it was for aesthetic reasons and for fun ("donuts everywhere" style). The 💡&&⭕⭕➜🍩🍩 part was just to illustrate, it has no functionality in the code.
u/tomxor

I think Pavel might be refering to unicode tofu, I get this too... the "⭕⭕➜🍩🍩" bit renders but almost all the other non-ASCII chars are tofu. I think it depends on what browser/OS combo you have.
u/tomxor

... and which fonts you've bothered installing.
