Less obtrusive eater-5 [12] Traffic light and glider [2]

Eater-5 is an eater that can eat gliders, but unlike Eater-1, that sits right in the middle of the glider's path, Eater-5 sits off to the side, making it more useful for picking off gliders from one stream that is very close to another, with an offset of as few as 9 cells. The less obtrusive Eater-5 is slightly larger and more expensive, but can also pick off gliders from one stream 8 cells away from another.



Other sizes: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26 and larger, not quite stable objects.
