Constructing a labyrinth in 3D is an easy task, but achieving a harmonious result needs a little bit more effort.
Cutting out a 3D labyrinth from a the block results in several related parts, some of which can be combined in surprising sculptures.
I found that sculptures based on labyrinths with more than one turn are not only difficult to make by simple means but also lose visual transparency and posses little charm for artistic enjoyment.
