With the advent of the touch-interface the concept of regular do it yourself seems obsolete. That is till you take a look at The Quartz Tele concept by Tao Ma. Incorporating large quartz crystals for each numeric number on a dial pad, the crystals emit the embedded LED lights when you press them. Giving a very surreal, nay Krypton-gadget like feel, the phone even displays info like incoming calls, dates, and contacts.
