The following account was recorded in the agent's log during your transmission: Graffiti-covered skateboard ramps cover the entire surface of this massive, abandoned waterpark. Umm, it's super humid in here and the air smells like chlorine and coconut sunscreen, with this weird, slightly metallic tang... A giant, intact model of the 120-cell, this four-dimensional polyhedron, is sitting at the bottom of the wave pool, and it's somehow creating a perpetual motion of waves that never dissipate. The sun is straight overhead, so it's probably noon or something, and the light reflecting off the water is casting this insane, fractal-like pattern on the ramps.
