Hypercard is a graphical card "stack" oriented application and database programming tool for the Apple Macintosh. It features hypertext and hyperlinking of graphics and buttons, and includes an easy to use scripting language called HyperTalk. In many ways, it resembled a web browser, however it had no networking capability.
It was released in 1987, and for a time was included with all new Macintosh computers. As such, use became quite wide spread and popular. It was used to create many commercial applications, most notably the game Myst.
There was also a release for the Apple II GS.
