Time isn't the only measure. And in terms of space, I don't think you're accounting for all of it.
When you make universe scenes bigger, you tend to see GC pressure. This *suggests* to me that there is not a lot of sharing from one display to the next; rather, an entire WIDTHxHEIGHT bitmap is being generated (and thrown away) each time. Yet I'm pretty certain this is not how the DOM works. That means the space difference is much more than the space for representing the circles. At least on laptops, increasing the size of the scene seems to induce more GC, and for large enough images the GC can actually induce a pause in an animation. I'm pretty sure this is a qualitative difference between the two models.
