The Gonihedric 3D Ising model is a lattice spin model in which planar Peierls boundaries between + and - spins can be created at zero energy cost. Instead of weighting the area of boundaries as the case for the usual 3D Ising model with nearest neighbour interactions, the edges or ``bends'' in an interface are weighted, which is related to the intrinsic curvature of the boundaries in the continuum. \\
In this talk we review the history of the model, before moving on to the elucidation of the equilibrium phase diagram by various means and the investigation of the non-equilibrium behaviour of the model, which turns out to display many glassy features.
