For those lamenting the passing of Hypercard, there's still SuperCard, LiveCode, and Decker.
SuperCard is Mac-only, fairly true to HyperCard, but with color and additional widgets built-in.
LiveCode is Mac, Windows, and Unix, and deploys for Android and iOS (and web I think, although I don't know how capable that is as I haven't tried it much). It starts from HyperCard, but has grown significantly from there, with many additional UI and language features.
Decker is mostly true to HyperCard from a UI standpoint -- it barely has color as far as I can see. But its language is not at all HyperTalk. And it runs entirely on the web, and nicely so.
