Similarly, I've been wondering what's at the core of a GUI? It seems in recent years that more people have been moving towards web-based applications, and away from traditional GUIs, so the meaning of them may be changing. The old question seemed to be Page vs. Control-Board, but that seems like implementation, when the real essence of a GUI is taking in common kinds of user input and displaying output in a sensible way. Similarly, there are more ways to interact with a computer than ever before, from simple keyboard up through multitouch interfaces like the iPhone. It would be cool to me to see a semantic model that captures this. 2009/2/3 Conal Elliott <conal@conal.net>:

I've been wondering for a while now what a well-designed alternative to CSS could be, where well-designed would mean consistent, composable, orthogonal, functional, based on an elegantly compelling semantic model (denotational).
