    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.

Cool! how about a texture on it? for(j=w=c.width|=N=60,x.fillRect(68,N,18,w);j--;x.fillRect(X+4*(X*Y/8e3)+90,Y+X/9*S(Y/N+X/N-7*t)+70,s=(X|Y)%256*.06,s))X=j%N*15,Y=j/N*15

A binary clock. The value p can be changed to resize a lamp(square) while the "1" int the third row can be changed to speed up the clock. The order is left(hours), center(minutes), right(seconds)

hmmm

u/tomxor

Haha, regex cannot parse an AST... also: }{a = 1
u/tomxor

I take that back, not sure what's going on, can't see much happening in between textarea and eval in iframe.
u/tomxor

Ahh, i get it: function u(t) {} {a=1} the end part is valid if it's an object literal or ES6 destructuring.
u/tomxor

You could actually use this for intialisation variables instead of checking !t... might be smaller
u/tomxor

i.e }{a=1 rather than !t||(a=1) (saves 4 chars)
