A new model of inflation is described. An unusual form for the inflationary potential is obtained because the inflaton corresponds to a non-trivial path in the configuration space of the two real scalar fields of the model. The model predicts a spectral index $n = 1 - 3/2N \simeq 0.97$ for the density perturbations and negligible gravitational waves.
