The caterpillar is the first 17c/45 spaceship that was constructed. It was created via a combination of manually-constructed parts put together by David Bell, Jason Summers and Gabriel Nivasch and a computer-aided construction coded by Nivasch. The caterpillar's construction took place over a long period of time, but it was completed on December 31, 2004.
Caterpillar is, in terms of its 11,880,063 alive cells, by far the largest interesting pattern that has been constructed in Life. By comparison, the Spartan universal computer-constructor has a larger bounding box, but only half a million live cells. The image to the right is zoomed out to a scale of 32 cells per pixel and still only shows the top 3% of it. Encoded as an RLE file, it is over 29Mb in size.
