Serious Game Classification

The Atari Cosmos was an unreleased product by Atari Inc. for the handheld/tabletop electronic game system market that uses holography to improve the display. It is similar to other small electronic games of the era that used a simple LED-based display, but superimposes a two-layer holographic image over the LEDs for effect. Two small lights lite up one or both of the holographic images depending on the game state. The system was never released, and is now a coveted collector's item.
