(split$,,shift.pop.shift))[map{hex}split$\,pop]}->(map y{#-`}{+-]}r,qw&
...../. (aa(+f*(,-0+e)-cb ../// ////..*. e/-0d+,b0.*ad1*a)d.+c(*af&)&0_
…in fact, I quit Twitter months ago.
The online O’RLY book-cover meme generator only emulates the “classic” O’Reilly layout, but this picture seemed to cry out for a more modern look. Fortunately I did the first one in Illustrator, making it trivial to update.
