`vector'?  You mean a bunch of boxes, right :-)

Hmm.  This means that


       +---+
       |   |
       |   |
       +---+


becomes essentially

        +-----+
       /       \
      |         |
      |         |
       \       /
        +-----+

right?  If you say `expanded by x' do you mean x/2 on each side?

Example, please.
