Let's put lots of hard marble angles in a place with a hard marble floor that gets water dripped on it all the time because my money makes me invincible.
Is it even a sink or a portal to another dimension? This would be a great opening for a horror movie - where someone gets sucked thru in the first scene.
Gah! Is that…shark’s teeth? ::enlarges photo:: Looks like rocks or crystals of some sort! Not a mirror frame choice I would have made, but yes, the sink is very interesting!
