Simple Floating Clock is exactly what the name implies. When Apple released Mac OS X 10.5 Leopard, they removed the option to show the clock in a floating, translucent window on the desktop. Some people liked that view so I decided to give it back
It's a clock. A simple, floating analog clock that sits on your desktop any where you'd like to put it. It works on Mac OS X 10.6 and up. It may run on 10.5, but only on Intel machines.
Because Apple got rid of that option in the stock clock with the release of Leopard (Mac OS X 10.5) on October 26, 2007. Some people like it.
Well, yeah. You can customize it a bit if you open the Preferences window with a control-click or right-click on the clock face. There's really not much to do to a clock and still leave it useful, though.
