Sometimes Im amazed at how stupid I am: 'filter:invert(';for(let z,A,B,n,X,Y,i=24;i;X+=A,Y+=B)(40+X/48^16+Y/48)%15>1?x.fillRect(X,Y,n/++z**.5,1/8):(z=1,r=(n+7)**i*t,A=2*S(r),B=2*C(r),--n)||(n=8,X=1280+i*S(t),Y=720+i*C(t),--i);

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/geb

for(i=1e4;i--;f(0,c=2,280,i+t,💡&&⭕⭕➜🍩🍩)) f=(w,h,q,d)=>q>99?f(h+q*C(d),w+q*S(d),q/c,T(d*d+t*d)/c): x.fillRect(w+480+950*(i%c),h+510,.4,t<c)
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.
