The "Sea" textured Dichrolam is available in rigid or flexible sheets in glass or abrasion-resistant acrylic, with a lamination on the underside of a hand - patterned dichroic (color-changing) material exhibiting a wavy "viening" effect that simulates a cross between water waves and fine burled wood veneer. In the closeup photo above of 'Black Sea' Dichrolam, this highly topographic 3D texture is completely random and resembles the natural viening of marble.
