Snail-shaped keyboard
This weird gadget which seems like a snail is actually a keyboard. It comes with a unique loop responding to your hands movement. The loop has a 5:1 gearbox, which means you can only move 1/5 distance to touch the same key in conventional keybaord.
You may find that there are only three rows of keys on the interior loop. Actually, it also features a standard qwerty keyboard. Because it uses the unique tri-directional keys, a single key in this loop can function as three keys of normal keyboard.
