A clock! I couldn't golf it enough to get varying line widths for the hands

u/joeytwiddle

Suggestion: c.width|=0;[1440,60,1].map((h,i)=>{e=300+100*i,f=t*.105/h,x.lineWidth=5,x.moveTo(960,540),x.lineTo(960+e*S(f),540-e*C(f)),x.stroke()})

Thank you! What a smart solution.

btw: that ratio 97:56 is a freakingly good approximation of the square root of 3

Golfed down by 11 characters. Can someone make this green?

u/magna

Can shave another 2 by: i=半=500
u/magna

Need to shave another 11 to fit c.style.background='#0f0'. Playing with x.fillStyle could be more expensive because of the need to switch back to black.
u/magna

Shaved down to 119: https://www.dwitter.net/d/2376
