ConTeXt is a great TeX format specially since Metapost is tightly integrated into it that producing page numbering style like

is easily implemented if you know Metapost (which I admit I don't, but learning). The following is the code, copied and pasted from documentation sources which produced this page numbering style.

\setuppapersize[A4][A4]
\setuplayout[topspace=0.5in, backspace=1in, header=24pt, footer=36pt,
  height=middle, width=middle]

\def\MPclipFive#1#2#3#4%
  {\startreusableMPgraphic{clip:five:#1#2#3#4}{}
     %
     delta  := #4;
     width  := #1-delta;
     height := #2-delta;
     lines  := #3;
     %
     z1 = (0,0);
     z2 = (lines,0);
     z3 = (.5width,height);
     z4 = (width-lines,0);
     z5 = (width,0);
     %
     pickup pencircle
       xscaled delta
       yscaled .5delta
       rotated 30;
     %
     draw z1--z2{dir 135}...z3...{dir -135}z4--z5 withcolor (.5,.5,.5);
     %
     pickup pencircle
       scaled delta;
     %
     draw z1 withcolor red;

Much as I like to work everything else with ConTeXt, I am afraid my skills are not up to par with that from my LaTeX experience to do some of the typesetting that I usually do, specially with math and tikz graphics. Thankfully, one can do Metapost inside LaTeX with the gmp package. I have successfully used egreg's example for using gmp for the fancy heading but I can't work out the details for the page numbering due to my lack of understanding, I think, of how \sbox and \mpdim works. I am thinking of using fancyhdr to integrate the Metapost graphic to achieve the effect. Here is a MWE to play with.

\documentclass[10pt]{article}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[shellescape,tex]{gmp}
\usepackage{xcolor}

\usepackage{titlesec}

\def\MPclipOne#1#2#3#4#5{\begin{mpost}
      w := #1;  width  := 100;  wfactor := w/width;
      h := #2;  height := 100;  hfactor := h/height;
      color lightred;  lightred  := (.90,.50,.50);
      color lightgray; lightgray := (.95,.95,.95);
      color gray;      gray      := (.50,.50,.50);
      def random_delta (expr d) =
        d-(uniformdeviate 2d)
      enddef;
      z1 = (0,height);
      z2 = (0,0);
      z3 = (width,0);
      z4 = (width,height);
      z5 = (width+random_delta(.2width),height+random_delta(.2height));
      z6 = (.5width+random_delta(.1width),height+random_delta(.1height));
      pickup pencircle
        xscaled (#3/wfactor)
        yscaled (#3/(2*hfactor))
        rotated 30;
      draw z5..z1..z2..z3..z4..z6 withcolor #4;
      pickup pencircle
        xscaled (#3/wfactor)
        yscaled (#3/hfactor);
      draw z1 withcolor #5;
      draw z2 withcolor #5;
      draw z3 withcolor #5;
      draw z4 withcolor #5;
      draw z5 withcolor #5;
      draw z6 withcolor #5;
      newwidth  := (xpart (urcorner currentpicture)) -
                   (xpart (llcorner currentpicture));
      newheight := (ypart (urcorner currentpicture)) -
                   (ypart (llcorner currentpicture));
      currentpicture := currentpicture
       xscaled (w/newwidth) yscaled (h/newheight);
    \end{mpost}}

\def\MPclipFive#1#2#3#4%
  {\begin{mpost}
     %
     delta  := #4;
     width  := #1-delta;
     height := #2-delta;
     lines  := #3;
     %
     z1 = (0,0);
     z2 = (lines,0);
     z3 = (.5width,height);
     z4 = (width-lines,0);
     z5 = (width,0);
     %
     pickup pencircle
       xscaled delta
       yscaled .5delta
       rotated 30;
     %
     draw z1--z2{dir 135}...z3...{dir -135}z4--z5 withcolor (.5,.5,.5);
     %
     pickup pencircle
       scaled delta;
     %
     draw z1 withcolor red;
     draw z2 withcolor red;
     draw z3 withcolor red;
     draw z4 withcolor red;
     draw z5 withcolor red;
     %
   \end{mpost}}

% I want to combine this with fancyhdr, perhaps, to get the desired result.

\newsavebox{\tacopage}
\newcommand{\tacopagenumber}[1]{%
\sbox\tacopage{#1}%
{\ooalign{%
\MPclipFive{\mpdim{\wd\tacopage}} % width
{\mpdim{\ht\tacopage}} % height
{12}
% thickness of the curve
{(.7,.7,.7)}
% color of the curve
{red}
% color of the spots
\cr\hfill
%\raisebox{\dimexpr.15\ht\tacopage+1.5pc\relax}
{\box\tacopage}\hfill
}}}

% For the section formatting

\newsavebox{\tacochapterbox}
\newcommand{\tacochapterhead}[1]{%
\sbox\tacochapterbox{\Large\bfseries #1}%
{\ooalign{%
\MPclipOne{\mpdim{\wd\tacochapterbox+6pc}} % width
{\mpdim{\ht\tacochapterbox+3pc}} % height
{8}
% thickness of the curve
{(.7,.7,.7)}
% color of the curve
{red}
% color of the spots
\cr\hfill\raisebox{\dimexpr.5\ht\tacochapterbox+1.5pc\relax}
{\box\tacochapterbox}\hfill}}}

\newcommand{\secformat}[1]{\tacochapterhead{\thesection\ \raisebox{-4pt}{\textcolor{green}{\rule{1pt}{\baselineskip}}}\ #1}}
\titleformat{name=\section}[block]
{\large\bfseries\filcenter}{}{0pt}{\secformat}
\titleformat{name=\section,numberless}[block]
{\large\bfseries\filcenter}{}{0pt}{\tacochapterhead}

\begin{document}


%\maketitle
\section{A section}

\tacopagenumber{a try}

\end{document}

which produces the output:

Can't help with the actual question, but I'd like to mention that ConTeXt can handle math and tikz just fine. –  Aditya Apr 10 '13 at 3:29
