This looks so much like a WebGL dweet but it isn't.

Shortened by 10 characters: c.height|= p=m=>(S(Y+t+m*90)+1)*250;for(i=108;i--,Y=(0|i/4)*40;a<b&&x.fillRect(a,Y,b-a,40))x.fillStyle=R(a=p(m=i%4),50,b=p(m+1%4))
u/Purpzie

Oh woops it should be c.height|=p=m=>(S(Y+t+m*90)+1)*250;for(i=108;i--,Y=(0|i/4)*40;a<b&&x.fillRect(a,Y,b-a,40))x.fillStyle=R(a=p(m=i%4),50,b=p(m+1%4))
u/Purpzie

Okay dwitter hates me now, there should be a newline afterc.height|=
u/Purpzie

Honestly there should be an edit button for comments. Forgot to mention I changed the color but it has no effect on code length

By saving golfing 2 characters I managed to make the twister bigger:

A little more movement: c.width=a=2e3;for(i=2*a;i--;)d=C(p=S(t)*i/a+i%4/.637)-S(p),d>0&&x.fillRect(a/2+199*S(p)+399*C(t),i/4,199*d,1/(d+1)),x.fillStyle=R(i/9,d*a/8)
