I have this:

```
\usepackage{picins}
\shadowthickness{2pt}
\newcommand{\sidenote}[1]{
    \begin{center}
    \hpic(0.95\textwidth,0pt)[rs]{
        \parbox[b]{0.9\textwidth}{\small
             \bigskip{#1}\bigskip
        }
    }
    \end{center}
}

```

Which generates a nice (shadowed) box with padding. The problem is that `\sidenote` cannot accept formatted text (i.e. paragraphs). 

Is it possible to define a "FancyRemark" *environment* which has the same visual style but does allow for paragraphs and display style math?
