    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.

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);

Grass in the wind

u/jwc

Uncompressed: z=(s=(v=t%14.57)<2)?0:v-2;for(c.width|=j=16;j--;)for(k=20;k--;)for(i=25;i--;x.fillRect(w+2*(q=24-i)*C(3*z+i/24-w/4e3)*(1.5+C(z))+(s?q:0)*S(56.55*v+i/24),550+k*k+i*6,i/5,6))w=128*j+k%2.3*56
u/jwc

Now that I’ve accepted that this will probably never fit in 140 chars uncompressed, I might consider working on smoothing the transition when the strong wind starts and stops…
