Does anyone know the equations of the cards suits?

I'm looking for the equations of the cards suits.

This link below presents some equations for the heart curve
http://www.mathematische-basteleien.de/heart.htm

But I didn't found the equations of the other three suits.
Does anyone know where can I find these equations?

Thanks in advance.

Very funny, but I don't want the TeX equations!

I need the cartesian or parametric equations.

I figured as much, but I couldn't resist. You might have to "roll your own". I'm curious what your application for those equations is.
