Hehe, Paul, that's what I call a simplified equation! I can see where you're coming from though with their design ideas. I keep thinking about these as the topic goes on, these are definately my favourite new Stretch piece so far (from the pics at least), and I like the look of them more than most of the other fashion glasses like the Riddle. So, for me in terms of O's fashion stuff, these come a close second to Dartboards.
Having said this, I'll probably see/try them on and not like them. But I'm optimistic at the moment.
