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 part, while also reading and moving a construction tape. As the name suggests, this creates somewhat paradoxical design, similar to the 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.
Caterloopillars with many other speeds can be constructed using slightly modified design. The major limitation is upper bound of c/4 speed, as the signal transferring is done by converting still life into glider and back, thus limiting the moving speed of the tape by c/4 (which is the speed of the glider).
