I'm not sure if anybody has found this glitch, or if it's posted, but here goes. All you have to do is ride the sellbot factory silo lift (cooler with the west silo) to the top. As soon as it starts down, run off the left side while rapidly pressing the "home" key (to make the computer lag). If all goes well, you'll be walking above the factory! Just don't walk over any pathways or... nvm. Just don't do it.
