HyperCard Making a Comeback
HyperCard was a development platform on the Mac that featured some of the ideas that were used in the foundations of the web (things like the hyperlink and element scripting). It also was the first platform that I really got into developing for. The programs you write for it work kinda like a slide show that can be improved by scripting elements you place on each slide (things like buttons or fields to switch slides or do lookups and calculations).
Anyway, this website is implementing a web based version of it. It looks pretty interesting and they are making the scripting for it (called Speak) to be almost fully backwards compatible to HyperTalk (HyperCard’s built-in language). I signed up for the beta but haven’t got my invitation yet to try it out. Looks like it could be fun.
