What a fun paper, but seems like a cute joke to me. All that the author did was use the basic wave equation with changed variables to simulate Jell-O. The article has algorithm and theory tags, but this is neither. I wish they had gone into detail about the numerical algorithm used to simulate the wave equation in three dimensions (Runga-Kutta order 4 probably?). As someone with a physics background, this is far from theory, or even original research. It's interesting that they mention the necessity of Markov Chains for intersection calculations. Would anyone know if better techniques have been devised since the publication of this paper?
