This rug is right up my alley namely because it's in a greyscale and also reminiscent of an animal hide (without acutally using animal hide) I saw this Spine rug featured in Hospitality Design Magazine. It was conceptualized by fashion designer Camilla Staerk fo Normann Copenhagen which I just recently familiarized myself with.
Normann Copenhagen has an amazing design store in, of course, Copenhagen that I would love to visit. The building they are in was an old water distillery turned theater turned sound studio turned store. I'm sure it's worth a visit! Go here to look through their site and see their other fun products!
