Aurora

Macs can wake you up like a zombie the same way any regular alarm clock can, but you'll need it turned on.

Aurora is an alarm clock for Macs that lets you use a song or an iTunes playlist as a wake up call. It can also use a radio station or an EyeTV television channel.

The application can even wake up your computer -- if it's already asleep or turned off and then turn it on -- although you'll need the administrator's privileges.

You'll need to set the time that you want to wake up and the days that the alarm goes off. You can set more than one.

The next step consists of what the program does after you turn the alarm off for the first time. You can even do this with your Apple Remote.

In the end, Aurora makes an excellent tool for keeping you from tucking yourself back in after the alarm goes off and it even works if you left the computer on or turned it off.
