The human thumb has a really dynamic movement, the opposing movements working together make the thumb more functional than a single finger. The Third Thumb replicates these movements by using two motors pulling against the natural tension of a flexible 3d printed material. The motors are controlled by two pressure sensors retrofitted into your shoes, under your toes, and communicate to the thumb via Bluetooth connection.

I'm holding out for the "All Thumbs" model.

Kind of like the Neosapiens from the '90s cartoon, Exosquad. (They only had three fingers, and two opposed thumbs.)
The iPhone 10 will require a third thumb. Genius.
