  We study a simple model supporting domain walls which possess two
orientational moduli in addition to the conventional translational modulus.
This model is conceptually close to Witten's cosmic strings. We observe an
$O(3)$ sigma model on the wall world volume in the low-energy limit. We solve
(numerically) classical static equations of motion and find the wall profile
functions and the value of the coupling of the $O(3)$ model in terms of the
bulk parameters. In the second part a term describing a spin-orbit interaction
in the bulk is added, which gives rise to an entanglement between rotational
and translational moduli. The corresponding extra term in the low-energy
Lagrangian is calculated.
