Summary description: Draw articulated quadrilaterals
Announcement text: ----------------------------------------------------------------------
An Articulated Quadrilateral is a four-bar linkage mechanism (four rods connected by hinges) that changes shape as its joints move, creating complex, predictable motions used in machines like pedal cranks, lamps, and even for generating curves.
