OMMATIDIA

Overview

Each compound eye of a large dragonfly is composed of up to 30,000 ommatidia. Each ommatidium collects visual information through photoreceptors, and together the thousands of ommatidia help form a mosaic image in the dragonfly’s brain. These images of images—taken from hundreds of Icelandic road webcams—form a mosaic record of light, time and physical/psychic landscapes.
