More real physical behavior of icons

I love the idea of BumpTop to give icons physical behavior.
This gives a way better feeling for the desktop and the work on it.

I'm just bothered by the feeling of the physics in BumpTop.
The icons feel sluggish. The seem to glide over the desktop and move like on some kind of ice.
Not like real objects.
It would be great to see the physic engine behind BumpTop revised, so that the icons move more fluid and feel more like realworld objects.

I hope you know what I mean :?

Again I have to refer to "RealDesktop" that I have tested, too.
I don't like this way of competition, but the physical behavior of ther icons feels great.

But be assured, I like Bumptop way more ;)
