The first super computer that Rohit Mehra invents is visually different from the super computer that is reinvented based on the first one. Keyboard of first super computer rests on a metallic stand where as later one appears as it is simply floating in air. The first super computer is operated by left hand where as later super computer is operated by right hand.
