Focus for Mac

From Eerko Vissering:

Did you ever wonder what your frontmost application is? You've just quit a couple, switched a couple of times with command-tab, and closed a window and now you're not completely sure if its application was closed as well.

You take a look at the Dock, but nothing gives away the frontmost application. You see a couple of them are running, but which one will quit if your itching fingers hit command-Q? You can always look at the menu, of course, but wouldn't it be easier to see an icon instead of only text?

All Focus does, is show you the active application's icon, with an optional analog or digital clock. Because its function is that simple, I've thrown in the usual junk of customizability: size, transparency, position on screen and window layering can all be adjusted to your needs.
