btw orignal Creator is Sindre Sorhus -- try this var _log = console.log; console.log = function() { _log.call(console, '%c' + [].slice.call(arguments).join(' '), 'color:transparent;text-shadow:0 0 2px rgba(0,0,0,.5);'); };

Then run some console.log("Hello Console") or other statements after executing the function above and see the prank ;)
