Rifeland is a vast, brightly lit space occupied by elementary shapes done up in primary colors. It is like being inside an educational toy designed to teach solid geometry to three-year-olds: cubes, spheres, tetrahedrons, polyhedrons, connected with a web of cylinders and lines and helices. But in this case, it has gone way, way out of control, as if every Tinkertoy set and Lego block ever made had been slapped together according to some long-forgotten scheme.
