bobwrit sends us to Wired for a look back by the author of HyperCard, Bill Atkinson. Quoting: "HyperCard is a programming environment that can create applications as diverse as utilities and games by linking 'cards' arranged into 'stacks.' Commands are executed through a natural-language scripting language called HyperTalk... The software has been phenomenally successful and highly influential. But Atkinson feels that if only he'd realized separate cards and stacks could be linked on different people's machines through the Net — instead of cards and stacks on a particular machine — he would have created the first Internet browser."
