A lot of these modern HyperCard reinterpretations get stuck on the black-and-white aesthetics of the original. That's cool, but it limits how broadly appealing they become. Even back when HyperCard was relevant, Apple's inability to properly introduce color as a first-class feature was what effectively killed the product.

A few years ago, I think there would have been a market for a HyperCard-inspired tool that targeted modern technologies - probably web tech.

Today, I guess vibecoding is what HyperCard was in the 80s and 90s, the tool you can use to quickly and easily build a little program that fills your specific need.
