# pst-fourbarlinkage: 

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, functioning as a simple, 
one-degree-of-freedom system with fascinating, non-intuitive movements 
and applications in engineering. 

PSTricks is PostScript Tricks, the documentation cannot be run
with pdftex, use the sequence latex->dvips->ps2pdf or lualatex,
which is a bit slow for animations but the easiest way.
To view the animations use the AdobeReader or convert it to gif.
