lithophane การใช้

Window lithophane panel scenes change throughout the day depending upon the amount of sunlight.
A lithophane presents a three-dimensional image-completely different from two-dimensional engravings and daguerreotypes that are " flat ".
In this lithophane portrait he is sitting at a small desk holding a " Belt Pistol " in his right hand and has a directional compass in his left hand.
From this is derived a meaning for lithophane of " light in stone " or to " appear in stone " as the three-dimensional image appears suddenly when lit with a back light source.
The word " lithophane " derives from Greek " litho ", which is from " lithos " which means stone or rock, and " phainein " meaning " to cause to appear " or " to cause to appear suddenly ".
