Copy cylinder around Z then twist it up

Hello all,
I'm a newbe on openscad.
I want to copy a cylinder around Z then copy it upwards. That's working but
I cannot get a twist in.

The first cylinder is:

module Zylinder ()
{ rotate ([90,0,0]) cylinder (h = 30, r=3 , $fn=6); }

Then I copy it around Z:

module FirstLayer()
{ for(a=[0 : 90 : 270])  rotate(a) Zylinder(); }

Until here it is working. I have 4 Cylinders like a cross.
But how can I copy the whole cross up let's say 20mm and twist it let's say
30° so I have the copied one 30° "twisted"?

YESSSSSSS !!!!!!!

for(z=[ 0 : 10 : 60 ])

translate([0,0,z])

for(a=[0 : 90 : 270 ])

rotate(a+z)

rotate ([90,0,0]) cylinder (h = 30, r=3, $fn=6);

Now it looks like this:
