Back in 2007, Software MacKiev bought HyperStudio. They’ve been working on it since with the original creator of the application, Roger Wagner. They’ve finally released the product of their hard work in Roger Wagner’s HyperStudio 5. It’s important that you remember the first part of that. I tried out Roger Moore’s HyperStudio 5, but the constant reminders to see Quantum of Solace were just too much.
Multimedia is a big part of this Hypercard competitor with support for podcasting, webcams, and imports from iTunes, Keynote, Youtube, and old HyperStudio stacks. There are tools for text and image manipulation. This latest version can be yours for a mere $89.95.
You called HyperStudio a "HyperCard competitor" but, alas, the competition is over, since HyperCard was killed by Apple when it wasn't updated for Mac OS X.
I don't mean offense to the niceties of Keynote, by I would trade it in without a nanosecond of thinking if I were to have back on Mac OS X even just the equivalent of Hypercard 2.3!
Anyway, I think I'll look better into HyperStudio.
My memory of HyperStudio is that it was more flexible than HyperCard. It contained a programming language for truly sophisticated results, but many of the features (going all the way back to the late '80s for its original platform, the Apple IIGS) were intuitively accessible. My young children were able to create decent stacks, as were relatively uncomputer-savvy high school students. Alas, Apple the Suicidal Corporation was determined to kill the IIGS and so "force" school districts to use Macs instead (most actually chose to go PC instead); and one of the great forerunner computer programs never got a chance to exploit its edge.
