Sure the graphic was only thought as a placeholder.

Yes I did. But I see a problem with only surrounding "worked"-tiles:
          - - -
X X X    | | | |
          - - -
X . X -> | | | |
          - - -
X X X    | | | |
          - - -
(X: "worked"-; .:"unworked"-tile)

Would look exactly the same as:
          - - -
X X X    | | | |
          - - -
X X X -> | | | |
          - - -
X X X    | | | |          - - -
(X: "worked"-; .:"unworked"-tile)

This could be solved in marking what side of the line is "inside".
Another option would be only marking the "outmost" border. Meaning drawing a 
line read if and only if one adjacent tile is "worked" and the other is 
"unworked". thus the two situation from above would look like:

 - - -
|     |
   -
| | | |
   -
|     |
 - - -
and
 - - -
|     |

|     |

|     |
 - - -

But there might still be ambiguous situations.
