A floating highly-detailed (as far as 90s rendering software could allow) reflective 3D shape (as said in the title) among other, smaller and less significant objects in a middle of completely flat static world with surface made out of checkered glossy tiled floor texture and black skybox (so it would be easier to spare some memory and CPU to load the existing data), rumors tell somewhere around there is a physical simulation of mathematically-correct water and a teapot resting near.
