I just put the wraps on one of my projects. This one was a site scrapper and a site rebuild. Scraping means the site which controls the data did not provide an API or other means to get the data so using PHP, cURL, and AJAX (in this case, jQuery), I retrieved the data, used PHP and regular expressions to parse the data to use only the parts I needed, and CSS to present it correctly. The rebuild was applying a new design, furnished by the client, to the rest of the site. Overall fun, albeit with some speed bumps and hiccups.
