#hex #clock

u/f8f82804

the font is from d/11960
u/f8f82804

Each tick takes 256/1000 sec, so each pair of digits gives a value 0-255 in units of 4.66 hours, 1.092 minutes, and 0.256 seconds, respectively.
u/f8f82804

The whole clock only rolls over once every 49.71 days.

#minimal #outrun #glitch #sunset -- remixed and heavily golfed for a black background

u/f8f82804

should work correctly in browsers such as #safari and #edge that don't support shortened hsl(xx yy%zz% color strings
u/pavel

FYI you can drop the closing ) in the hsl, just not the s and l separator.
u/f8f82804

u/pavel: IIRC #edge requires the closing paren -- see https://github.com/lionleaf/dwitter/issues/3… (which hilariously enough references one of my very first dweets) and d/9170
u/f8f82804

oooof that link got mangled -- https://github.com/lionleaf/dwitter/issues/3…

Omitting the space in 99%50% does not work in Safari, everything is black.
u/f8f82804

yeah safari stinks

try "for(c.width|=i=384;i--;x.fillRect(960-w/2+e,4*i,w+e,4))y=i/80-2,w=y>.7?3e3:(1-y*y)**.5*640,e=T(t/9+i*w),x.fillStyle=hsl(${-y}rad 99% 50%)" which should work and is still <140
