Does anyone know of a LaTeX package that implements a visual counter similar to the countdown counter of this context-module? It produces images like this:
However, I would like to stick to LaTeX and beamer, so if anyone has used/hacked together something similar, I would appreciate any reference.
I am aware of the progress bar theme, but I would like to add such a circular progressbar to my own theme.
If just want to draw it, you might want to check this. I've just fixed some stuff about it (now it checks the parameters given, and sends warning if necessary).

You can also create an enumeration environment (in a bit hack way):

\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]

}
\end{tikzpicture}

A solution in Beamer (inspired @masu answer, but with clockwise increments).
It actually can be used both in Beamer or in non-presentation documents: the user selects where it is convenient one or the other option via the key beamer. Usually it is set to false allowing the selection of current and total value parameters. When beamer=true, the latter parameters are overridden by the Beamer settings \insertframenumber and \inserttotalframenumber.

It is just for fun with PSTricks and not a complete solution. The remaining part should be easy to add.
