Those are some great ideas that dovetail together in powerful ways! Thanks you for sharing your work in progress.
In the hopes of inspiring you and others, here's a kind of messy draft of an article I haven't completely finished, but it's all about HyperLook (a user-editable desktop GUI system inspired by HyperCard and implemented in NeWS PostScript) and some components and applications I developed with it, like SimCity, a cellular automata machine, pie menus, a customizable clock editor, a customizable window manager, and "Happy Tool":
SimCity, Cellular Automata, and Happy Tool for HyperLook (nee HyperNeWS (nee GoodNeWS))
HyperLook was like HyperCard for NeWS, with PostScript graphics and scripting plus networking. Here are three unique and wacky examples that plug together to show what HyperNeWS was all about, and where we could go in the future!
