Yes, HyperCard spawned a number of clones, notably Supercard: http://www.supercard.us/supercard/index.html http://www.supercard.us/supercard/index.html and MetaCard: http://en.wikipedia.org/wiki/Metacard http://en.wikipedia.org/wiki/Metacard (The latter evolved considerably, was acquired by Runtime Revolution http://www.runrev.com/ http://www.runrev.com/ and is now called LiveCode; it's sold as a rapid application deployment platform on desktop OSs, iOS and Android.) Supercard is noteworthy because it supports direct import of Hypercard stacks (the Supertalk language is a superset of Hypertalk). There are other Hypercard like systems out there. For example, on iOS/iPad there's NovoCard -- a Hypercard like system for iOS that uses JavaScript for scripting: http://plectrum.com/novocard/ http://plectrum.com/novocard/
