Trilithon Protractors is a feature-rich application for Mac OS X that is designed to meet the needs of web developers and graphic designers. It provides precision measurement of angles with scales that include Degrees (360 gradations in a circle), Radians (2? gradations in a circle), Grads (400 gradations in a circle), Mils (6400 gradations in a circle), and Compass Rose (32 principal points). Measurements can be set to Widdershins (anti-clockwise--the standard direction).
