The Gonihedric Ising model originates from catching basic properties of fluctuating random surfaces in a bosonic string theory. Formulated as a lattice model of interacting classical spins it can be investigated by means of the multicanonical Monte Carlo algorithm to resolve open questions on the first-order phase transition. The transition temperature has been determined for the model and a dual representation; also the interface tension has been measured for both models and appears to be quite strong.
