visural-wicket is a useful set of light-weight, loosely coupled components and utilities for the Apache Wicket Web framework. Each component is designed to be easily integrated into any existing Wicket application with minimal dependencies. Each component is also designed to be easily customized to fit a particular system's requirements. Other than components, visural-wicket includes some other utilities that assist in the development of Wicket applications, such as an annotation-based mounting system, model templates, and an automatic "form view mode" component.
Google Calendar Chrome Extension adds a button to your browser toolbar that displays a preview of your calendar while you're navigating. (works on any page). If you're on certain sites where it detects the presence of events, the icon changes to a green "+". Clicking that icon lets you add the event to your Google Calendar, and shows you a Map (if there's a location it could detect.) Supported sites include Facebook, Evite, and any site that uses the hCalendar microformat or derivative microformats such as hResume.
