Spongerooms, part 2. The same yellow corridor carved out of an infinite Menger sponge, raymarched in a single GLSL shader. You walk past an ivory and ebony yin-yang, and at the second intersection the floor is missing. You stop at the edge, look down, and step off. A new level of corridors passes every second as you fall, and space bends harder the deeper you go.
