u/rep_movsd

v=Math.random x.fillStyle='#d964' if(v()<.9)i=v()*1920,j=v()*1080 for(k=99;k--;){x.fillRect(i,j,6*v(),80*v()) i+=(j-540)/(70 +v()*10) j+=S((i-960)/70) }
u/BackendForth

Neat! You can actually drop the "if(v()<.2)" altogether and tweak k=99 for some extra characters

zensaiyuki: I found this trick for generating a 16 color palette: i*0x775511. i wonder if it can be made smaller in javascript.

u/iverjo

Neat. To begin with, you can replace 0x775511 with 7820561. Further, you can look into bit operations or modulo to truncate/slice the string
