Best Desktop Clock App?

I bought a new Galaxy S3 and dock. I am look for a good desktop clock app with night functionality. I setup the dock on my night stand and would like to be able to plug in my phone and have it automatically pop up a very dim clock suitable for a nightstand. I have tried a couple and they are either too bright or don't move the clock around the screen. I don't want burn in or a night light effect. Any suggestions?
