I am surprised that they used yahoo pipes as an example for "flow based" programming instead of something a bit more modern such as Node Red (1). My own experience wit trying to design a flow based system for mobile (http://flowgrid.org http://flowgrid.org) was that input seemed just to cumbersome (compared to typing) and not dense enough (compared to text) -- at least on mobile.... Labview / lego would probably be worth looking into, too.... 1) http://nodered.org http://nodered.org
