It's ok to eval if when it's medieval
u/tomxor

Soz had to replace other one due to chrome rendering bug, faster in FireFox
u/erin

this is great tom! crazy to see i've started this
u/tomxor

Thanks :) it's still the same principle you started, new_core and I just squeezed and textured it.
u/erin

lol thanks!
u/tomxor

I got the description wrong, this is not medieval but an #ancient #chinese #flag design... hard to find a definitive source of historic flag designs to reference

Nano Snakeskin

u/bandaloo

this is great! i'll definitely be using this substitute for a doubly-nested for loop
u/DataMeta

agreed, cool trick! even more succinct than the nested hack I've been using, and the perf increase from bitwise ops is welcome
u/tomxor

Yes, I've used this so much, I guess it's just more obvious in this one. I've taken technique a step further in d/20707 converting yonatan's 3 loops into one. bitwise can be very powerful to manipulate the variables a loop traverses.

This was a tough golf! thanks for the challenge and awesome dweet yonatan :)

I like this golfed rendition! :]
u/yonatan

i think i like this better than the original :)
u/yonatan

what's the deal with the k^64 tho? seems like it'd spend 64 iterations building the fbm in T and then 64 more doing fillRects??
u/yonatan

k&63 I'd understand...
u/yonatan

oh right, k isn't the loop counter

-1 char with i&7: for(c.width=64,i=2e4;Z=--i>>9;T=i&7?T+S(Z+C*k/9+9/Z*t*k)/k:x.fillRect(C=i/8&63,T*9-T*Z/3,1,l=Z*32-Z*Z,x.fillStyle=R(l,l+Z,l/.8))|3)k=1<<i%8
