Bedri Baykam has grasped the lenticular process, a technique whose material seed has been around for 4-5 decades; He readapted it through a mixture of materials and optical fields with the help of several processes which allow to develop many layers, going sometimes up to 50! The new technique, that he chose to call 4D, (Three dimension + “Time”, the 4th dimensional vector bringing together the past, the present and the future) has raised a lot of interest around the world since 2007.
