Frogs (video game)

Frogs is a 1978 action video game developed and published by Gremlin Industries for arcades. It featured a jumping character (predating Donkey Kong by three years) with graphics "projected" by laying the monitor flat on its back and reflecting the computer-generated graphics of the frogs and flies toward the player via a mirror at a 45-degree angle. The game's graphics were actually generated and shown backward, so the mirror reflection would show letters and numbers properly. The game was distributed by Sega in Japan.
