I sometimes like to use unary plus purely for aesthetic reasons.

That is, the following:

coordinates.push_back(new Vector(-w,-h));
coordinates.push_back(new Vector(+w,-h));
coordinates.push_back(new Vector(+w,+h));
coordinates.push_back(new Vector(-w,+h));

..looks nicer to me than:

coordinates.push_back(new Vector(-w,-h));
coordinates.push_back(new Vector(w,-h));
coordinates.push_back(new Vector(w,h));
coordinates.push_back(new Vector(-w,h));

Of course, I could (should?) always use whitespace...
