I love this! I don't know if you have plans to keep working on it, but I would like to leave my feedback here anyway.
When the clock looses focus the numbers stop moving until you click on it again. Not sure if it was inteded that way, but it kills my idea of having the clock runing as a wallpaper int the background.
Having an option to keep it at the tray instead of the taskbar would be great too, and being able to toggle the background used in the screenshot and banner would make it perfect.
Again, great and beautiful work!
