Tesla S charger station features a charger 'arm' (officially called the "Solid Metal Snake"), which is made of 18 flexible segments. It moves, bends and kind of slithers like a snake (or a creature from Dr. Who) completely automatically towards the parked Tesla S charging port, aligns itself perfectly, then connects with the port.

This is only a prototype, meaning it's not exactly available for some 1-click purchase, so we shouldn't get all worked up just yet. However, this may change soon. Namely, on December 31 last year Tesla CEO Elon Musk tweeted: "Btw, we are actually working on a charger that automatically moves out from the wall & connects like a solid metal snake. For realz." Obviously, he's a man of his word!
