Epic Floor Design, although I'm not sure what the idea is. if laid with clear or glass tiles to see the design would be different, but to put black tiles over doesn't make any sense. I wonder if you get a magnifying glass to view the floor.
Some people are epic. (Although, this is a perfect example of why I think Life of Pi shouldn't have been nominated for anything other than best animation. I'm a hater, but only when it comes to that movie.) I have mad respect for visual effects artists!
