Caterloopillar is the name given to a family of spaceships containing two parts - the front and the back. In Caterloopillar each part has the properties of universal construction, and thus each part is constructing the building blocks of the other one, while also reading and moving the construction tape. As the name suggests, this creates somewhat paradoxical design, similar to strange loop concept.
The first Caterloopillar was constructed by Michael Simkin and completed on April 9, 2016. This Caterloopillar has the speed of c/8, but arbitrary speeds strictly less than c/4 can be realized.
