Heart Curve: Happy Valentines Day!

As the world enters Valentine's Day (February 14, 2014), you can mathematically express your love by drawing the heart curve, which comes from the family of cardiod curves.  

What is graphed is one of the heart curves:

x = 16*(sin(t))^3
y = 13*cos(t)-5*cos(2*t)-2*cos(3*t)-cos(4*t)
-2*π ≤ t ≤ 2*π
