...if you've ever watched Kubrick's classic SF film, "2001 -- A Space Odyssey", you've heard the Eltro in action(!). It's a story I don't think has ever been told before now -- here's how it happened. The sentient computer in Arthur C. Clarke's story is called HAL (and no, Clarke did not plan the name to be the three letters of IBM shifted one place to the left -- that myth overlooks an even lovelier example of serendipitous coincidence!). In the film the role was voiced by Canadian actor, Douglas Rain, who was able to give a cool, detached -- yet feelingful duality to the character. Here's a publicity photo of Rain taken from around that time.
