HyperCard, the graphical hyperlinked Mac app that influenced the invention of the Web, was invented by Apple engineer Bill Atkinson after an acid trip 30 years ago this weekend. Now the Internet Archive has brought it back with a collection of over 3000 hypercard "stacks" that you can explore right in your browser. Each stack opens inside the Archive's emulator of an early Macintosh computer.
You can explore stacks such as a guide to Seinfeld, origami instructions, chemistry clip art, a music sequencer, a tarot card reader, and an ebook of Bram Stoker's Dracula. Each one feels like a grainy CD-ROM or early web page. The browser interface takes a few minutes to boot up and runs pretty clunky, but you can download the stacks and run them on your own Macintosh System 7 emulator.
