This is another thing I love about the web. I found this on the RapidWeaver Forums and thought it was an intriguing way to showcase data. Enter the URL you wish to have reviewed and this site will generate a visual representation of your site. It reviews the code and generates the image based on several criteria: H1 is brighter than H2 is brighter than H3, etc., table is brighter than TR which is brighter than TD, DIV layout is brighter than a table layout, and on. A semantically coded site will appear brighter than an invalid page.
