Diatoms is a puzzly tile-placement and pattern-making game where players create their own microscopic mosaic, based on an obscure Victorian art form. Hidden in the water all around us are tiny lifeforms known as “diatoms.” These microscopic algae cells come in a variety of exquisite geometric shapes and patterns. Their outer layer is made with silica, giving them a glass-like quality. Here at the Society for the Microscopic Arts, we collect these diatoms and delicately arrange them on slides into beautiful, tiny mosaics. As part of your induction into the Society, you will each create your own entry for today’s Exhibition of Microscopic Mosaics.
