We review recent results for the low-lying glueball spectrum on the three-sphere in intermediate volumes that incorporate instanton effects. The latter are implemented through boundary conditions on the fundamental domain obtained by minimising the norm of the gauge field along the gauge orbit. Non-perturbative corrections due to the boundary conditions in field space are seen to be crucial.
