Twinkle Bulbs

Twinkle Bulbs is an application that allows users to decorate their desktop with light bulbs, wallpapers and screensavers.

The program is fully customizable and very easy to use. It sits in the system tray and enables users to control everything from there. It includes multiple types of bulbs to satisfy different tastes. The bulbs are very suitable for holidays like birthdays, Christmas, Easter, etc. You can customize the bulbs colors, style, flashing mode, location on the desktop, etc. You can also add music to your desktop with the ten holiday songs available or add your own ones.
The application also includes 4 screensavers, but they are not very good. As regards the desktop backgrounds, there are nine available, all featuring a holiday theme; you can also add your own images.
One thing I really like about the program is a customizable calendar which can be added to your desktop with a countdown to multiple holidays. You can also add special days or custom holidays of your country to the calendar.
As you can see, the program is very complete and customizable, and definitely deserves a try.
