Hi Angel,

Just from experimenting with your page, it seems that the first  
example you give spins around an axis going through the center of the  
view port (as the origin), while the version with two points for the  
axis orientation uses the atomic coordinate space.

Just try (I am making it go very fast so it is easier to see around  
which axis the rotation is occurring)
spin axisangle {1 0 0} 1000
spin axisangle {0 1 0} 1000
spin axisangle {0 0 1} 1000

Cheers,
René
