This Surfboard Photo Could Be the Next "The Dress" Debate: Do You See Bumps or Grooves?

So here's what Adolfo, who is selling the surfboard, told POPSUGAR in an email.

"It's kind of a combination, to my understanding of the process. When the final coat is applied to the board, the pattern is created in the resin, so the wax is filling in some depressions, but the wax is also protruding as it's layered on. I'm not really an expert, but this is the way I've understood it as it's been explained to me."

For those nonsurfers out there, you wax the deck of the surfboard to create bumps for better traction for your feet when you're standing on the board, and over time the wax accumulates on the board, creating bumps. But in this case, it's . . . both? Regardless of what it actually is, it's still pretty trippy that they either look distinctly like bumps or like grooves. The investigation continues!
