UI long term development perspective: physics engine

[Florent THIERY]

Take a look @ this iphone video:

There is:
- it's as if the entire list is the scrolling bar, but reverted
(finger down -> scroll up)
- the list follows the pointer
- as soon as you stop touching, the list continues to scroll (in
contrary to standard gtk scrolling bar)
- the list moves at the speed measured at the end of the "touching"
- some "friction" lets it slow down
- when you touch it again, it stops the scrolling

Questions:
- will the neo/openmoko graphics system be powerful enough for such
animation? I suspect apple to do opengl acceleration on this device,
which is waaaaay impossible for us
- ok, akamaru is overkill. But it allows friction, speed etc...
