Tiny LCD screens on your thumbs combined with miniature cameras on your thumb-pads would effectively create invisible thumbs, allowing you to efficiently text on phones where you are unfamiliar with the keypad.-- djmips, May 11 2006 Are you trying to tell me that some phones do not have: [1][2][3] [4][5][6] [7][8][9] [*][0][#]-- methinksnot, May 11 2006 While I think little screens on your fingernails would be kinda fun, that's such a mundane use for them, it cancels out my croissant.
