Gemini is the first oblique spaceship to be constructed, and was created by Andrew J. Wade in 2010.[1][2] It displaces itself by 5,120 cells vertically and 1,024 cells horizontally every 33,699,586 generations, and is therefore an ibisship. It derives its name from the latin, gemini, meaning twins, describing its 2 identical halves, each of which contains three Chapman-Greene construction arms. A tape of gliders continually relays between the two halves, instructing each to delete its parent and construct a daughter configuration.

It is the largest spaceship in terms of its diameter and bounding box, but has a much smaller population than the Caterpillar.

The pattern marks the thirteenth explicitly-constructed spaceship velocity, but facilitates an infinite range of related velocities. For example, Dave Greene has reduced its period by eight generations, whilst maintaining its displacement. Theoretically speaking, a Gemini-esque spaceship could be constructed with any velocity slower than (but not equal to) (1,1)c/580.[3] In June 2010, Greene also constructed slope-2 and slope-3 versions of the spaceship.[4][5]

Gemini was voted Pattern of the Year 2010 on the ConwayLife.com forums.[6]
