I try to explain rotating galaxy vortices by foreground rotation of the 
frame of reference of the observer.

In this case a vortex is actually a structure of significant depth, 
where stars are stacked in distance, hence also 'stacked in time' (in 
the image).

This would cause an apparent rotation of the vortex, while actually the 
foreground rotates, because a rotating observer would see remote stars 
at a different position than not so remote stars (still far away).

Since depth in space is difficult to measure, it is an understandable 
error to ascribe the same depth to stars in a vortex formation, even if 
the central stars are much further away.

If now a structure with very large depth is 'flattened' to the image of 
such a structure, the question would arise, why that structure does not 
fly apart, if it rotates that fast.

The answer would be: because the observer rotates and not the vortex.
