Was messing around today and found this little glitch that enables you to be outside the room map, I know you used to be able to do it with one way gates, but didn't think you could since they fixed that awhile back.
Just grab a furni that you can't usually sit/stand on, set up wired to teleport to it, and depending on what direction it's rotated, you'll teleport alongside it.
Sorry if it's been posted, hadn't seen this method before. Shrug.
