Clicked random and remixed the first dweet

u/scwaller

I clicked random and this was the first dweet, thought it would be funny to remix although I'm not very good at it

I'm guessing you are doing somthing like this (no peeking): for(c.width|=w=128,i=64;i--;x.font='4cm a')(X=i%8)%2==(Y=i>>3)%2||x.fillRect(X*w,Y*w,w,w);x.fillStyle='red',x.fillText('♛',w*3*S(t)+w*3,w*4)
u/danny@hille.dk

not even remotely close :-)
