    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.

fucking awesome!
u/Purpzie

Shaved 10 characters but it's super laggy: for(c.width|=0,i=572;Y=(0|i/13)*27,X=(572-i)%13,i--;x.stroke())x.lineTo(X*160+(X&1?C(2*t+Y/108)*120:0)*(X&2?1:-1),Y-(X&1?108:0))
u/Purpzie

Less laggy version that's 4 characters shorter instead of 10: for(c.width|=0,Y=1188;x.moveTo(0,Y),Y-=27;x.stroke())for(X=0;X++<13;)x.lineTo(X*160+(X&1?C(2*t+Y/108)*120:0)*(X&2?1:-1),Y-(X&1?108:0))

wtf!
u/donbright

the reflection thing is great!
u/recursive

wow, what?
u/sfz

shaved some bytes by replacing Math.PI/2 with 1.57, have fun remixing!
u/sfz

Also r=480;c.width=r*4 to c.width|=r=480 ... down to 130
u/mxfh

c.width|=r=540 for(λ=φ=a=1.57;φ>-a;)x.arc(C(φ)*S(t-λ)*r+960,(C(t+=a/r)*S(φ)+S(t)*C(φ-=a/r/2)*C(λ-t))*r+r,0,λ+=a,0) x.fill()
u/mxfh

thanks, using the angle offsets in arc gives another two possible spots for variable assignment at a radius of 0, so you get something equivalent at 123
u/sigveseb

Is that the same reflection technique as in https://www.dwitter.net/d/915 ?
u/mxfh

should be, I assume it's that negative winding on polygons messes with the fill rule evaluation
u/mxfh

just to clarify, fill rules looks allright, it's really just non-covered areas due to the zig-zagging of the fill. try a lower decrement like φ-=a/r*8 to see the more graspable source of the effect
