Big Hero 6: into the portal

In the climactic sequence of Big Hero 6, Hiro pilots his robot Baymax into the out-of-control teleportation device which has just destroyed the Krei-tech corporation campus. Once we pass through the portal, our challenge was to visualize a gap between the folds of spacetime fabric---we imagined a realm of fractal forms inspired partly by theories of spacetime structure found in an approach to quantum gravity known as causal dynamical triangulation.
