A car turning on a curved is known as curvilinear motion.
A curvilinear pattern is a curvilinear shape ( a shape made completely of curved lines. no straight lines/edges) repeated across a plane.

It has three sides.
A random walk is opposite in all senses. A straight line is only a curvilinear path with all the "higher order" terms set to zero.
