The "umwelt" comic was even more complicated than that. It had different versions based on: * location (getting surprisingly specific sometimes) * browser * what plugins work/don't work in your browser * referrer (what you clicked on to arrive at the comic) * operating system * screen size * browser window size * hostname domain (i.e. you're at work, and your company's domain) * hostname TLD (i.e. your computer's ISP is .net, .mil, etc) Here are different compilations of the variations he created: http://www.explainxkcd.com/wiki/index.php?title=1037:_Umwelt http://www.explainxkcd.com/wiki/index.php?title=1037:_Umwelt http://imgur.com/a/faLz2 http://imgur.com/a/faLz2 I'm not nitpicking, just helping demonstrate how far Randall went in that creation.
