  A Photon Collider will provide unique opportunities to study the SM Higgs
boson and to determine its properties. MSSM Higgs bosons can be discovered at
the Photon Collider for scenarios where they might escape detection at the LHC.
As an example for the many other physics topics which can be studied at a
Photon Collider, recent results on Non-Commutative Field Theories are also
discussed.
