I guess at this point, I just see a nice VPL; it seems to have the liveness properties of Quartz Composer, at least, which, as you say, displays an interactive results visualization and input data widgets (though you might have to turn the patch around or mouse over an input pin). It seems to fit into Tanimoto's liveness level 4 taxonomy.

If you have some direct manipulation and gradual abstraction going on, I haven't seen it in your examples or explained in your docs.
