In fact, enigma_conf.lua isn't really necessary anymore, unless someone
really needs a systemwide configuration file for Enigma.

I tried it. Frankly: it feels horrible :-) I'm not sure how to describe
it... maybe "unbalanced" is the right word.  Either the marble
accelerates too much, even when you move the mouse only slightly, or it
doesn't move at all.

I'm not too happy with damping either, but it was the best solution so
far.  The problem is that Enigma uses variable time steps--introducing
the damping factor made the acceleration more or less
framerate-independant.  The current CVS version fixes the time step of
the physics simulation to 15ms, so it may be possible to (finally) get
rid of the damping; I will try that later.

Incidentally, fixing the time step made everything else behave much
better.  The current CVS version with damping=50,friction=1,speed=4
feels "just right", if you ask me.

Cheers,
Daniel
