Pamela Anderson, 33, clearly no stranger to unveiling things, showed off something new yesterday: the "PortaPam" computer program. The product enables a scantily clad cartoon version of the former "Baywatch" babe to be downloaded onto tiny digital organizers. "I think my fans will enjoy playing with PortaPam and helping manage (their careers) on their hand-held computers," said Anderson, as quoted by the Associated Press. What to do with a PortaPam? Keep the Pam icon happy. This works when the user clicks on lists of food, gifts or affectionate remarks . . . and then gets to see PortaPam blow kisses and dance in a nightclub. Look, it's only five bucks.
