  In this talk I present the latest results of the ESTER project that has taken
up the challenge of building two dimensional (axisymmetric) models of stars
rotating at any rotation rate. In particular, I focus on main sequence massive
and intermediate mass stars. I show what should be expected in such stars as
far as the differential rotation and the associated meridional circulation are
concerned, notably the emergence of a Stewartson layer along the tangent
cylinder of the core. I also indicate what may be inferred about the evolution
of an intermediate-mass star at constant angular momentum and how Be stars may
form. I finally give some comparisons between models and observations of the
gravity darkening on some nearby fast rotators as it has been derived from
interferometric observations. In passing, I also discuss how 2D models can help
to recover the fundamental parameters of a star.
