Block quote with big quotation marks
Here's one solution using TikZ which defines a new environment using the framed package. You should preferably compile this with xelatex or lualatex, since it gives the easiest access to a wide range of fonts. I've added code to make it run under pdflatex as well.
The code has now been updated to allow some flexibility in the formatting of the different components of the quotation, and the environment takes two arguments:
Environment Syntax
\begin{shadequote}[<alignment>]{<author>} text of quote \end{shadequote}

\usepackage{fontspec}
\usepackage{libertine} % or use \setmainfont to choose any font on your system

\else
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{libertine} % or any other font package
\newcommand*\quotefont{\fontfamily{LinuxLibertineT-LF}} % selects Libertine as the quote font
\fi
\newcommand*\quotesize{60} % if quote size changes, need a way to make shifts relative
% Make commands for the quotes
\newcommand*{\openquote}
{\tikz[remember picture,overlay,xshift=-4ex,yshift=-2.5ex]

\newcommand*{\closequote}[1]
{\tikz[remember picture,overlay,xshift=4ex,yshift={#1}]

\begin{document}
\begin{shadequote}[l]{Douglas Adams}

\end{shadequote}
\begin{shadequote}[r]{Douglas Adams}

\end{shadequote}
\begin{shadequote}[c]{Douglas Adams}

\begin{shadequote}{}

\end{shadequote}
\end{document}
In this code, the font for the quotation marks is set independently of the main document font. This is because depending on the main font you choose, the very large quotation marks will not look good; Linux Libertine has pretty quotes that seem appropriate for the purpose. If you want to use this environment with another main document font, remove/change the \usepackage{libertine}.
Sample output
(We just got another question asking for something similar: Quote style like on owni.eu. I wasn't aware of this question when I started to answer that one, but on becoming aware of it decided to post my answer here instead.)
It's also TikZ-based but slightly different to Alan's as the whole thing ends up in a TikZ node. This does mean that it won't work with page-breaking. One could also adapt the quote marks from Alan's version to make them look a bit better.
Here's the result:
And here's the code:

The lipsum package is just to provide some dummy text.
