In previous work with Carel Faber and Gerard van der Geer, we showed how invariant theory can be used to generate all Siegel modular forms of degree 2 and 3. In this talk,
we will explain how invariant theory can again be used to construct all Picard modular forms in the case of signature (2,1). This is a joint work with Gerard van der Geer.
