Fancy bullet lists with TikZ

At the end of October there was a question on TSX on how to create visually appealing counters in LaTeX documents. One of the answers (by Sandor Kazi) was the following:

\documentclass{beamer}
 
 
\usepackage{enumitem}
\usepackage{refcount}
\usepackage{tikz}
    \usetikzlibrary{calc}
 
\makeatletter
\newcommand\statuslabel[3][]{%
    \def\scale{#1}
    \ifx\scale\empty\def\scale{1}\fi
 
    \let\no\relax
    \let\n\relax
    \newcommand \no {#2}
    \newcommand \n {#3}
    \def \colorbef {blue}
    \def \colorat {orange}
    \def \coloraft {black!40}
 
    \let\stop\relax
    \sbox\z@{\@tempcnta=0\no\relax}\ifdim\wd0>\z@\relax\@latex@warning{Not a number (\#2): \no}\def\stop{1}\fi
    \sbox\z@{\@tempcnta=0\n\relax}\ifdim\wd0>\z@\relax\@latex@warning{Not a number (\#3): \n}\def\stop{1}\fi
    \ifx\stop\relax
        \ifnum\no>\n\@latex@warning{Wrong parameter order?}\def\stop{1}\fi
    \fi
 
    \ifx\stop\relax
    \else
        \def \no {1}
        \def \n {1}
        \def \colorat {red}
        \def \stop {??}
    \fi
 
    \begin{tikzpicture}[scale=0.1*\scale]
 
    \def \radiusout {2cm}
    \def \radiusin {1.3cm}
    \ifnum\n=1
        \def \margin {0}
    \else
        \def \margin {25/\n}
    \fi
 
    \foreach \s in {1,...,\n}
    {
        \node[circle, scale=\scale] at (0,0) {\tiny\stop};
        \fill[\ifnum\s>\no\coloraft\relax\else\ifnum\s<\no\colorbef\else\colorat\fi\fi]
            ({90-360/\n * (\s - 1)-\margin}:\radiusout) arc ({90-360/\n * (\s - 1)-\margin}:{90-360/\n * (\s)+\margin}:\radiusout) --
            ({90-360/\n * (\s)+\margin}:\radiusin) arc ({90-360/\n * (\s)+\margin}:{90-360/\n * (\s - 1)-\margin}:\radiusin);
    }
    \end{tikzpicture}
}
\makeatother
 
\makeatletter
\newcounter{myenum} % to create unique labels
\newenvironment{myenum}
  {\stepcounter{myenum}
   \edef\nref{\getrefnumber{myenum@\arabic{myenum}}}
   \edef\nref{\expandafter\@firstofone\nref}
   \begin{enumerate}[
     label=\protect\statuslabel{\arabic*}{\nref},
     ref=\arabic*]}
  {\label{myenum@\arabic{myenum}}%
   \end{enumerate}}
\makeatother
 
\begin{document}
 
\begin{frame}
 
\begin{myenum}
\item example
\item example
\item example
\item fsdfs
\end{myenum}
 
\end{frame}
 
\end{document}
