A recent analysis of the WMAP3 data has suggested that the temperature anisotropies imprinted at the last scattering surface could be as large as 1 part in 1000, almost 100 times larger than the predicted signal from single-field, slow-roll inflation. I will survey some models which lead to larger non-gaussianities and outline those areas where our knowledge remains incomplete.
