I made this snippet though its 144/140 chars: z=_=>S(t+_*Math.random())*255 for(i=3e3;i--;){r=t*t*S(t);x.fillStyle=R(z(i),z(i),z(i));x.fillRect(960+r*S(a=i/19),540+r*C(a),S(i+t*S(t))**8,t);}
u/ximavus

Analog Stopwatch ⏱️

u/cantelope

i?b/5 -> i?b for accurate minor hand motion. /5 chosen for aesthetics?
u/KilledByAPixel

yeah, i think this is pretty common for analog stopwatches because otherwise 1 per second is very fast

Nice but I wouldn't use it for the Olympics, over concerns about framedrops.

I will make a compressed version that is perfectly accurate for Olympic use.

Congratulations cantelope! You have won back 87% of your investment.

Why does it only render the cherries now? I don't think its a problem with the dweet but I glitched or something
u/KilledByAPixel

Wow, that is so weird, this dweet somehow broke itself.
u/KilledByAPixel

ah dang it, i remember now, sometimes the combination of the date and bitwise math causes it to go negative
u/ximavus

ohhhhhh

That's funny. I guess the question now is WHEN will it be fixed?
