From the developer:
BackgroundClock is a small app which lives in your menu bar. It helps you keep track of time by constantly displaying the current time in a digital format on your desktop. You can change the clock format to 12/24, show or hide clock seconds, change the clock's font size and the font color, and set the clock's opacity.
You may want to check out more Mac applications, such as iAlarm, MenuCalendarClock Entourage or Chronos, which might be similar to BackgroundClock.
