Curvilinear – A shape whose edge is dominated by curves. Curvilinear shapes can also be referred to as organic shapes, though organic shapes frequently reference “natural” curves whereas curvilinear shapes may reference synthetic or “perfect” curves in addition to “natural” curves (curvilinear is a more general definition than organic).
