iDomDig is an instant domain availability lookup which allow you to check for multiple domain availability for the extensions com, net and org. Pretty simple and useful AJAX usage in the application make the service run from a single page. DomDig uses its own AJAX library, and PHP at the server side to retrieve domain status via an API.

iPhlickr is an iPhone interface for Flickr photo service, using the Flickr API with PHP and YUI for the interface. The service allow you to login and check your photos, search by username or tags, or simply visit the latest added photos and today’s interesting photos.  I liked the sliding interface, but I was wondering why it’s not working on Firefox ? Because usually there is not a lots of compatibility problem. Strange if it’s optimized for iPhone, and broken for FF.
