Q:

Using Beamer bullets in poster

I am creating a LaTeX poster with the Baposter template, and would like to use the Beamer 3D bullet as my itemize bullet, like the one shown below:

Is there any way to achieve that?

A:

Thanks to @prettygully's comment and How to create a ball shading and to customize 3D lighting manually?, this is what I have achieved:

Code:
\documentclass{article}

\usepackage{tikz}

\newcommand{\colouredcircle}{%
  \tikz{\useasboundingbox (-0.2em,-0.32em) rectangle(0.2em,0.32em);
        \draw[ball color=blue,shading=ball,line width=0.03em] (0,0) circle(0.18em);}}
\renewcommand{\labelitemi}{\colouredcircle}

\begin{document}
\begin{itemize}
  \item Item 1.
  \item Item 2.
  \item Item 3.
  \item Item 4.
\end{itemize}
\end{document}
