I finally got the cube designed properly and loaded into Unity with the Vuforia Engine.  It took some time, but I learned what images were trackable.  I just took fractal images I found for free.  I uploaded the Unity package and the Android package for anyone that wants to test it or just play around.  It will require the Vuforia plugin for Unity. The cube can be printed from the photo posted.  I'll be adding different time telling methods for each face of the cube and updating the files again.
