ooooohhhh boy i got a lot on this one. i recently read the book again, and have revisited the entire series. in clarke's mind, the monoliths are the remnant ai machines of an ancient race that has long since evolved into a godlike state. originally, they were supposed to be the ultimate fusion of mind and technology, but he drifted into the hyper evolved ai concept as the series went on. their purpose was to find and nudge various life forms into higher forms of being for a nefarious purpose later revealed in a second series of books. in the book it used this weird light show to teach one tribe of ape men to conquer others. one waited on the moon for man to reach it, then pointed them to the stars.
the whole trippy light show at the end was the best they could do with 60's filmmaking. and it was also kubrick's interpretation as a director. also makes for classic parody. in the book bowman made a journey not unlike the final act in contact. kubrick did a neat thing showing the passage of time for bowman in that little room. basically bowman lived out the rest of his life in a cell that looked like a hotel room while the monolith gradually altered his conciseness. the fetus form at the end was meant to represent his rebirth as a godlike being. one of the coolest scenes in the book is when he appears over earth as a giant fetus. the planet's anti asteroid system launches a salvo of nukes at him. he barely thinks about them and they blow up.
HAl in the first and second movie/books had nothing to do with the monolith. he goes "crazy" because he was stuck in a moebius logic loop. HAl was designed to be the best it can be and serve it's human counterparts to the utmost. however, the military arm of the mission ordered him to keep the real nature of mission secret from bowman, poole, and the 3 guys in the freezer. hence, being an honest/loyal ai that was ordered to lie conflicted with his basic nature and drove him nuts. somewhere in the series, super space baby dave fuses himself, hal, and the europa monolith into one entity that lies dormant on europa. oh it gets even better.......but that's another story....
