Merge a calendar with your wallpaper, using Rainlendar
Rainlendar is a free calendar application that will place a calendar on your desktop merged with your wallpaper, to let you know the date, track events, setup reminders, etc. The appearance can be customized with skins and you can even mix different skins together. It is possible to use Rainlendar with other calendar applications too. Rainlendar uses the standard iCalendar format to store its events and tasks so you can easily transfer them between applications.
Rainlendar is a Unicode application and supports localization. All future events are shown in a separate list where you can see the week’s events at a glance. You can decide how many days in advance you want to see in the list.
Different events can have a different appearance in the list so you can easily spot the important events. The icons in the calendar are also available in the event list and other windows to make it easier for you to separate the events. You’ll also get an alarm when an event or task is due so that you don’t miss it. A commercial version offers more features.
