Abstract: We have prepared a degenerate gas of fermionic atoms which move in twodimensions while the motion in the third dimension is -frozen- by tightconfinement and low temperature. {\it In situ} imaging provides directmeasurement of the density profile and temperature. The gas is confined in adefect-free optical potential, and the interactions are widely tunable by meansof a Fano-Feshbach resonance. This system can be a starting point forexploration of 2D Fermi physics and critical phenomena in a pure, controllableenvironment.
