Here's a couple of cool sites relating to money for your web design inspiration.
Bank of Canada: Vertical 10
This microsite for the Bank of Canada highlights the new $10 Canadian bill. There's a couple of little glitches, but altogether it's a memorable site that encourages users to dive deep into the content. Cool cutouts, nice graphics, well compiled content.
