    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.

A torus-like shape made of sin and cos spinning in 3D space. Credit to u/Xen for golfing.

Better with transparency, but 148 bytes -- t?0:s=0;for(c.width|=a=1e3;a--;x.beginPath(x.globalAlpha=.5))x.ellipse(960+200*C(a),540+200*S(a),90+30*S(a+s),90+30*C(a),0,0,7),x.stroke(),s+=1e-4

I'm done --- t?0:s=0;for(c.width|=a=1e3;a--;x.stroke(),x.globalAlpha=.5)x.beginPath(),x.ellipse(960+200*C(a),540+200*S(a),90+30*S(a+s),90+30*C(a),0,0,7,x.strokeStyle=R(255*S(a)+255,255*C(a)+255,100+10*C(a))),s+=1e-4 --- 202 bytes, but full with colors and stuff, except for a weird bright area(?)... I dunno, see you all tommorow, I'm off to sleep :P

I golfed it to 134 chars with transparency. for(c.width|=a=1e3;a--;)with(x)ellipse(960+200*C(a),540+200*S(a),90+30*S(a+t*6.2),90+30*C(a),0,0,7),stroke(),beginPath(globalAlpha=.5)
