On September 3, 2016, The Scientific & Educational Centre «Primorsky Aquarium» was opened in Vladivostok on Russky Island. Two expositions using holographic pyramids were specially designed for the educational centre. The application is educational in nature and is a holographic pyramid with a three-dimensional image of unicellular and multicellular organisms. The holographic image is controlled by an additional touch panel, where the visitor can find comprehensive information about the simplest microorganisms that inhabit the world's oceans. This application is written in C# using Unity.
