There's no place like ::1

I will need this in the near future for sure:

\newenvironment{warn}
{
  \medskip
  \begin{minipage}[t]{0.1\linewidth}
    \vspace{0pt}
    \Huge{\Pointinghand}
  \end{minipage}%
  \begin{minipage}[t]{0.9\textwidth}
    \vspace{0pt}
    \begin{small}
}
{
  \end{small}
  \end{minipage}
  \medskip
}
