Larry Yaeger uses computers to solve hard and interesting problems, from flow fields over the space shuttle to special effects for “The Last Starfighter,” “2010” and “Labyrinth”; to providing a computer “voice” for Koko the gorilla; to developing the world’s first usable handwriting recognizer for second-generation Newtons and Mac OS X’s “Inkwell”; to evolving machine intelligence in an Artificial Life system called Polyworld. He teaches programming and Artificial Life at Indiana University, and plays videogames and reads and watches entirely too much science fiction. And is eternally grateful to Levi for putting up with him!
