My favourite invention (which i'd most like to see reappear in an up and coming Bond film) from the Bond series would have to be 'Little Nellie' - the mini copter that was used in 'You Only Live Twice' - i found it so cool as it was carried around in four suitcases and packed 'one hell of a punch' thanks to the addition of two front machine guns,two backward flamethrowers,two front rocket launchers,heat seeking missiles,aerial mines and two back producing smoke screens.
