Twelves and sixes

 
Covered in some holes
12x12x6x6 segments and rings cover

 
The layout of the segments, holes, and ridges of this 12x12x6x6 manhole cover could be adapted to a clock face.

  1. I notice that some of the holes on that manhole cover are covered over. Isn't there a city department that is supposed to be going around opening up those closed holes?
