Antstretchers and tubeaters

c/4 diagonal antstretcher, with an anteater of the same speed
Nicolay Beluchenko, 5 January 2006
After a long search, Nicolay Beluchenko has successfully found an 'antstretcher' pattern to match his previously discovered 'anteater'. Individual ants in the 'ants' wick supported between these two structures have an apparent speed of travel equal to the speed of light. Ants can either follow one another exactly, or can be offset by either one or two cells; in this case, the speed of the antstretcher and anteater dictate a one-cell offset between ants.

c/4 diagonal combined antstretcher and tubstretcher

Another new combination that has turned up is a connection between a tubstretcher and a tubeater, producing the interesting object at right. Further exploration of tubstretchers and tubeaters yielded the collection of new adjustable-length spaceships (and a puffer) shown below.
