Here's a concept phone for those who hunger for a more tactile and more visual experience when making a phone call (maybe the generation of younger adults who've never used a rotary phone). The Quartz Tele, designed by Tao Ma, uses quartz crystals embedded in LED for each dial pad number; the crystals light up when pressed. Looks like something you'd see in a movie made in the 1950s about the future.
