 As David and Steve prepare to launch in the alien crafts cockpit,  Davids laptop computer greets him with the spoken line "Good  Morning, Dave", and the image of an electronic camera eye. This is a  reference to, albeit a misquote of, the HAL 9000 sentient computer  ("HAL") from _2001: A Space Odyssey (1968)_ (qv) and his greeting to  crew member Dave Bowman. Although HAL never actually says "Good  morning, Dave" in the film, the electronic eye that appears on the  screen is indeed a picture of the HAL prop from the movie.
