UNIQUE & RARE has on offer a Glass "BUBBLEGRAM" - Giraffe Grazing in theTrees

Bubblegrams

A bubblegram (a.k.a. laser crystal, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that has been exposed to laser beams to generate three-dimensional designs inside.

How does it work?

Each point is created by a laser beam focused to high intensity at that location by a computer-controlled opto-mechanical system. A complex or highly detailed image occupying a 5 cm (2 inch) cubic volume typically requires the creation of tens of thousands of such points.

Bubblegram images may be created by intersecting laser beams in appropriately doped plastic to induce a chemical reaction via heat or photonic excitation, creating bubbles or nodes where the plastic has a different index of refraction.

Where did it originate?

Glass block bubblegrams of Russian origin entered international commerce as a novelty in the late 1990s, but high prices and the predominantly simple, inartistic subject matter severely limited market penetration until the 2000s.
