Recently
I purchased a 3D Photo Laser Crystal memento from Favouritely.com as
advertised in Face ( Photo above). I posted it in my FB page. I received
several comments and I become curious how it is made. The following
videos and article from Wikipedia is printed here for your information
and reading pleasure
A bubblegram (also known as 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. The image is composed of many small points of fracture or other visible deformations and appears to float inside the block.
Description
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.
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. In the early 2000s, a much less expensive, more visually appealing and highly diverse array of Chinese-made bubblegram novelties achieved wide commercial success in the United States, to the extent of becoming a fad: representations of monuments, corporate symbols, religious imagery, mythical creatures and nature scenes appeared in gift shops.
There also exist companies which will take custom photographs of people, convert them to a heightmap, then render that as a bubblegram memento.
