Keith Hook was a programmer at Millennium/Cyberlife/Creature Labs. He was responsible for the Macintosh port of Creatures and initial work on Creatures 2 for the Mac (the latter was contracted out, but never reached completion), as well as porting the Snowman Interactive Storybook to PC, for programming Daughter of Serpents and co-programming the Amazing Virtual Sea-Monkeys. After leaving Creature Labs (~early 2000) he may have worked at reALife UK, but no details are available.
