A bubblegram is a three dimensional image which is composed of points and remains suspended in a medium, usually a plastic block. Laser bubblegrams is in vogue. Crossing lasers in 'appropriately-doped' plastic, which may cause a chemical reaction through heat or 'photonic' inflammation, makes these images. It thus results in the creation of an air bubble or of plastic with a dissimilar 'index of refraction'.
Some special types of submerged laser 'etching' machines create bubblegrams. They use a single 'conically-focused' laser and thus forms 0.1 mm fractures within a glass blockage.
Use of this craft piece is unique. There are organizations, which would customize people's photographs, change them to a 'height map', and deliver them as a bubblegram. They use them as souvenirs for their companies.
Once developed as a typical art form of India bubblegram art has now crossed the barriers of countries and location and is now a well-accepted art technique for making souvenirs. In the lanes and by lanes of the urban cities like Mumbai and kolkata this bubblegram art form has carved a niche for itself whilst standing apart as an emblem of the rich cultural heritage of India.
