Beautiful visuals, poor app design
It’s beautiful, however, it’s actually a stand-alone app that runs "on top of" your current screensaver. (Not sure why the author didn’t write it as a screensaver that lives in the Scrensaver section of System Preferences.) So it’s a little awkward when you press a key to dismiss Clear Day only to see your login box appear with a deferent screensaver selected in System Preferences.
I also noticed Clear Day uses a good chunk of CPU while it’s inactive, which is unfortunate for laptop users.
Great design, please rewrite it as a real screensaver!
