Hi Bjoern,

maybe this one helps:

\documentclass{article}
\usepackage{pstricks}
\usepackage{pstricks-add}

\begin{document}
\newcommand{\squircle}[2]{
\psplot[algebraic,plotpoints=200,linecolor=#2]{-#1}{#1}{(#1^4-x^4)^0.25}
\psplot[algebraic,plotpoints=200,linecolor=#2]{-#1}{#1}{-(#1^4-x^4)^0.25}
}
% #1 = radius
% #2 = linecolor

\begin{pspicture}(-5,-4)(5,4)
\squircle{4}{blue}
\squircle{2}{red}
\squircle{1}{green}
\end{pspicture}
\end{document}

Regards,

Juergen
