..view the world thru a bottle of Perrier...
Now, there is novel a thought 
But the effect is very nice though. Now I know...Perrier bottle weighs 6.252kb...
Surely that must be overkill? Of course, you would not get your good rendering at proposed < 10kb models, but it should be interesting to see the .obj file. How many sides does the polygon have to simulate the circle? Gut feeling tells me that it could come down to <500kb or a whole lot less without noticeable quality loss - even in your rendering. ok
