I can't remember which game it was, but one of the arcade games used a set of basic chips to create a detailed vertical half of a spacecraft & the other half was mirrored over from the centerline due to space/current & chip cost constraints. When I had read about it, I marveled how absolutely ingenious early game developers were. Since I grew up in post-golden age of arcade, I don't really know which game that was - but I presume it was one of the Nolan Bushnell creations from vague recollection. Edit: It was Spacerace. From Wikipedia: >The engineering and prototyping for Asteroid was done by Alcorn. The game is encoded entirely in discrete electronic components, like Atari's earlier games, and unlike later computer-based arcade games; the graphics are all simple line elements with the exception of the spacecraft, which are generated based on diodes on the circuit board arranged in the shape of half of a ship to represent the shape they create [..] That half ship is mirrored on the screen, similar to the diode array in Computer Space, which generated eight directions of a rotating ship with a mirrored four images.
