u/SockTaters

u/Xor has a very clean 35b circle too: d/22669. There are some shorter circles, but they're blurrier: d/24291, d/24311. If you allow throw, you can get really tiny: d/18442
u/KilledByAPixel

the i in inch, nice one!
u/lewdev

I'm not seeing it on Windows 10. Must be a font issue. u/KilledByAPixel, thanks for explaining it.

(golfed -10b) 🌍🌝 Moon floating around earth (both rotating now)

u/SockTaters

not sure if this fixed or introduced a bug by rendering all 8 phases of the moon. It seems to fall out of phase fster
u/SockTaters

132b but no font string trick: for(x.fillRect(0,0,W=c.width|=i=2,W);i--;x.fillText([..."🌚🌒🌓🌔🌝🌖🌗🌘🌎🌍🌏"][i?t&7:8|t%3],(1+i*C(t))*800,i?670+S(t)*220:600))x.font="3in'"
