Alex, I'm lost as to what your current status is--what
you see as solved, and what questions still remain.
Do you see why the fragment above is unlikely to make
you happy?  after()'s second argument names a function;,
it doesn't expect the coder to invoke it.  Does the 
self-scheduling in <URL:
http://tkinter.unpythonic.net/wiki/after > make sense?
How did it not serve you better to write

     root.after(100000000, sleeper)

than what you have above?
