What is a modern successor to HyperCard?

Livecode went closed source and is out of the reach of most folks due to pricing.

Decker is too like to the original in being limited to b/w pixel graphics.

Flash afforded vector graphics and scripting, but is moribund.

Scratch only makes games and game-like things, with no ability to make traditional GUI elements.

Tcl/TK and Python/Tkinter lack integrated graphical development environments where one could just draw, while tools such as Lazarus and QTdesigner are too integrated with traditional textual programming. Processing similarly lacks a graphical representation of code or a drawing environment.

Nodebox and Ryven and so forth separate pretty graphics made of standard components and output.

If a naïve user wanted to express themselves by integrating drawing and numbers and code, what modern environment facilitates this?
