A self-constructing pattern is a pattern, generally a macro-spaceship, that contains encoded construction information about itself, and makes a complete copy of itself using those instructions. The Gemini, linear propagator, spiral growth patterns, Demonoids and Orthogonoids are examples of self-constructing patterns. Self-constructing spaceships often have trivially adjustable speeds. In many cases, the direction of travel can also be altered, less easily, by changing the encoded construction recipe.
