heal.abstract	We discuss the techniques to extract the electromagnetic Delta form factorsin Lattice QCD. We evaluate these form factors using dynamical fermions withsmallest pion mass of about 350 MeV. We pay particular attention to theextraction of the electric quadrupole form factor that signals a deformation ofthe Delta. The magnetic moment of the $\Delta$ is extrapolated using a	en
