I was thinking about a jumper mod. Like that movie: http://en.wikipedia.org/wiki/Jumper_(film) . In this mod, you would craft a camera. When you take pictures with this camera, you receive the pictures in your inventory. When you right click a wall with these pictures, you hang them up on the wall. When you look at the pictures for a few seconds, you get teleported to the location that that picture was taken at. Sounds very simple. I wonder if anyone can make it.
