    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.

It's one of those things that you can't tell whether it's rotating clockwise or anticlockwise

I think this is a bug with Dwitter and the code should work.

First time using setTransform, seems useful. .524/(a>3?5:1) is shortform for Math.PI * 2 / (a>3?60:24).

u/AnnanFay

Hmm, just noticed a few things. Would be smaller without with(x) since there's only two method calls. Also we don't need the 0| after the slice because the division will cast for us. So that's 7 characters.
u/akm

You can also remove some parentheses and the l variable: for(c.width|=a=12;a-=3;x.fillRect(-9,6,18,-a*50))x.setTransform(r=C(θ=Date().slice(13+a,15+a)*.524/(a>3?5:1)),n=S(θ),-n,r,960,540)

Impressive that you managed to fit both seconds and real hands. Seems I lack a bit of syntax creativity. Nicely done! :)

I'm not entirely sure this works, altough I spent quite some time on it. Had a hard time adjusting the angles for the different bases. (24 & 60)

Heh, nice! I notice I have a habit of remixing your work d/6801 It's not on purpose!

Incorporated improvements from 21medals and myself. Spent extra characters fixing the chomp rate so pac-man eats every square.

c.width|=τ=6.3,y=S(t%1*τ*2) puts this down to 134 bytes. Thanks to joeytwiddle.
