The 'Compass' System

A compass or, more properly, pair of compasses is a technical drawing instrument that can be used for inscribing circles or arcs. They can also be used as a tool to measure distances, in particular on maps. Compasses can be used for mathematics, drafting, navigation, and other purposes. [via wikipedia]
