I don't think spatially laying out symbolic code is likely to get that useful. We already heavily resist significant whitespace. I am fond of "ascii art" for tests and any code where it can help, but I get the impression I'm in the minority there. That said, expanding a palette to "things" that are placed in a very physical way makes sense. I'd suggest not thinking of it in terms of IDE, though. It is very common in CAD and other "editor" environments. Has been, for a long time, even.
