We report on a search for compositeness in ee gamma events and
a search for gauge-mediated supersymmetry in gamma gamma missing E(t)
events.  We also report on two signature-based searches for anomalous
production of gamma gamma + X (where X = e, mu, gamma, missing E(t))
and gamma l + X (where X = missing E(t), l, gamma).  The analyses are
based on 0.9-1.2 fb-1 of data from p anti-p collisions at sqrt s = 1.96
TeV collected with the CDF and D0 detectors at the Fermilab Tevatron.
No significant excess of data over the predicted background has been
observed.
