Callooh! Callay! A HyperCard clone that doesn't suck AND has programming in Python (rather than HyperTalk). Brilliant!

WyldCard

• HyperCard

Looks a really interesting Hypercard clone, but I'm unable to follow the compilation instructions. Shame.

• Authoring
• HyperCard

Based on Hypercard, this web-based authoring tool looks great. Except the Lil language is, er, not to my taste at all... And you can't (or I can't) just make a stack's size to be fullscreen... and why the hell does the UI fetishize Hypercard, rather than ape it brilliance. I could imagine making wonderful 1bit stuff with this, but it's LOCKED into recreating zombie Hypercard stacks rather than giving them new life. (imo)

Hypercard Stacks at archive.org

• HyperCard
• Scripting

HyperCard spawned so much creativity it's incredible. Just browse this collection to see some of the stacks created.  Archive.org has Mac emulators so you can now run these stacks as if it was 1987 on a MacPlus. 

Myst (first person shooter)

• Game
• HyperCard

You might not remember Myst, the ethereal game (created in HyperCard). This isn't that.
