Query: On certain families of planar patterns and fractals   This survey article is dedicated to some families of fractals that were
introduced and studied during the last decade, more precisely, families of
Sierpi\'nski carpets: limit net sets, generalised Sierpi\'nski carpets and
labyrinth fractals. We give a unifying approach of these fractals and several
of their topological and geometrical properties, by using the framework of
planar patterns.
