**In one line:** An x and a y bundled as an arrow — the unit of almost all motion.

## Theory, aesthetics & inspiration

A vector binds two numbers—an x and a y—into a single geometric object: an arrow possessing both magnitude (its length) and direction (where it points). This bundling is the atom from which all motion is built; position, velocity, and acceleration are each vectors, and the arithmetic on them—addition, scaling, normalization to unit length—becomes the grammar of movement. Daniel Shiffman's "The Nature of Code" opens here precisely because the abstraction is load-bearing: once a point becomes an arrow, a scene of static dots becomes a field of tendencies. The aesthetic is one of latent energy, of stillness already leaning toward somewhere.
