The Finger Touching phone concept is perfect if you’re not brave enough to have a phone embedded under your skin, yet still want to look trendy and futuristic. Granted you’d look dorky talking into your hand, hologram buttons or not.

The idea is that the phone’s keypad is projected onto your hand and the “buttons” separated by knuckles. Once you dial, you would hold your hand to your head a la the international “call me” pose. It’s a neat concept, but somehow it just wouldn’t fit into the Bionic Body Shop. Maybe the Cyborgism QVC Channel. [Yango Design]
