English: A 3D crystal engraving (a.k.a. bubblegram, laser crystal or vitrography) is a physically real three-dimensional image composed of many small points of fracture or other visible deformation within a solid block of glass or transparent plastic. Each point is created by a laser beam focused to high intensity at that location by a computer-controlled opto-mechanical system.
