Not exactly what you think.

Be warned, three of the five clock styles shown are available at EXTRA COST, which is not very clear at all. I bought this app for the Flip Clock style—not included. Repeatedly pressing “Purchase” from the Preferences menu (I already bought the thing, may as well pay the extra dollar to get the style I wanted in the first place,) does NOT take me to the App store, so I have been unable to purchase it so far. Kind of a ripoff. I would also REALLY like an option to turn off the Ken Burns zooming effect (which it does even in wallpaper mode). It is very distracting in the background.
