The members of my thesis committee were Jozsef Beck, Janos Komlos, Endre
Szemeredi and Michael Saks. Click here to see
what sentence emerged when I rearranged the letters of the Hungarian members
of my committee on the night before my defense.
This configuration (to the left) of 11 lines in the plane has the
property that no
line has more than 5 points of intersection. Since 5 = (11-1)/2, this
example is extremal in some sense. It is conjectured that, given any
configuration of n lines in the plane, some line will have at
least (n-1)/2 points of intersection on it. This problem is
still open, and I would love to see it proved or disproved. Note that
the configuration of lines is just a projective dual of the 11 points
shown to the right.

postscript file of a 7-dimensional cube, poset style.
And here you will find a (rather large, 713k) gif of the same figure..
