Description
In essence this works exactly like a lever, with the one exception that it 'imprints' on the first person that uses it. (hence it's basically a lever that only responds to a single person) This allows for a new way to secure advanced machines and bases. A truly clever person could use this as an 'override switch' to retake control of an advanced base or complex redstone wiring mechanism. Following this line of thought it would be nice to have the scanner stick well to sticky pistons (allowing it to come out of the wall, or floor like a boss ) -> Would have some limited use in SMP I think.
