^ Close your eyes, yell, "[your name] used TELEPORT!" then walk around for a while, as if to transport yourself manually. You'll feel like you're moving around - this is because you're teleporting. When you open your eyes. You'll miraculously be SOMEWHERE ELSE!
I haven't really honed this technique to select a specific position, allow long-distance teleportation, or guarantee that you won't find yourself colliding with MYSTERIOUS TELE-SPACE OBJECTS during the process, but it definitely works.
