A little discussion worth preserving: Sam Roberts brought up ruby -rtracer -rsocket -enil, which spits out source code as binary text. He called it the “DIY Matrix Screensaver,” which must have dug into the skin of some of the sig wizards out there, because now we have a couple of bona fide scripts that both disseminate Matrix line noise into a phrase along the lines of: eh, yeah, you could say I use Ruby.

From Jannis Harder:

 puts"\e[2J\e[0;11r";$stdout.sync=true;c='/,-=<>*+.:&%$'.split'';k=[nil]*25#
 z=0x1c59f7d252f3573e0e198b8f06470cbc5.to_s(?$).tr"xqzp"," JR,";p=0;while p<
 11;i=-1;print"\eM"*7,"\e[0;0H",k.map{|q|q ?" ":c[rand(13)]},"\e[6;0H",k.###
 map{|q|l=z[i+=1,1];q ?l:"\e[C"},"\n",k.map{|q|q ?" ":"\e[C"};k[rand(25)]=##
 true;sleep 0.1;k.compact.size>24&&p+=1;end;sleep 2;puts"\e[2J\e[r"+z##JIX##

From Brian Schroder:
