Query: Projected Products of Polytopes   We construct a 2-parameter family of 4-dimensional polytopes with extreme
combinatorial structure: In this family, the ``fatness'' of the f-vector gets
arbitrarily close to 9, the ``complexity'' (given by the flag vector) gets
arbitrarily close to 16.
  The polytopes are obtained from suitable deformed products of even polygons
by a projection to four-space.
