Like the others, I too find the layout and info overview is neat. Good use-case demo of real-time information scraping of the sale.<p>Also, like a few others, the "Perl" in your title is very interesting for me. As a Perl old timer working with a team that hasn't dabbled in any Perl at all, this would be a wonderful, wonderful hands-on demo of what Perl can and does do.<p>Is there a detailed technical write up on your blog, on how you did this in Perl? Is the code open-source, so I can show them with examples...etc?
