* Take the original idea of Hypercard and take it into the 21st century.
* Be completely open source.
* Export to HTML/CSS/JS and perhaps native for performance sensitive things.
* Would run as well on desktop as on mobile browsers.
* Maybe have a (subset) of Javascript, Lua or Python as a scripting language.
* Be as fun, easy and playful as the original.
Would definitely be something i'd support on a platform like Kickstarter.
The 2.0 version is a choose-your-own adventure generator that can go from simple (create 'pages', make one-way links between them) to complex (use CSS + Javascript to create multiple panes, keep track of variables, write graphics, etc), and it exports as a Tiddlywiki-based self-contained HTML file.
A minor nitpick but "native" is almost always unnecessary for this kind of programming. We have WebGL and soon, SIMD.js. Things are looking good on the performance front.
I think it'd be more important to focus on making WebGL support better on lower-end mobile devices or have a downgrade path to canvas or some other maguffin.
Maybe have a (subset) of Javascript, Lua or Python as a scripting language.
All of these languages are fine in their own right but they fall on the floor for being user-friendly when your user is someone whose vocabulary is not a part of the programming lexicon.
But they could be useful to people who do understand their models of execution.
I'd be more apt to suggest giving the users a kernel upon which any appropriate language can be integrated into the system for the user to select.
* Yes
* Community Version is open source
* On the LiveCode roadmap
* Compiles as a native app for iOS,Android,Mac,Win and soon HTML 5
* No, but ... the ability to wrap other languages and libraries and map them to HyperTalk is in development: http://livecode.com/blog/2014/07/08/the-next-generation-widg...
* Definitely as fun as the original
Sorry if I am coming off as a fan boy, but I read HN everyday, and this is the first time I've seen HyperCard/HyperTalk come up.
