The decorative Riddle on Friday: metal curve

Although Christmas, we don’t forget the decorative riddles and a Friday we want to challenge your deductive skills. The object I bring you today is intended for use in exterior and is made of carbon fibre.
You attract? What suggested it that curve winding? As track I will tell you that it is not a sculpture, but it is an object that is useful (putting a sculpture would be cheating, do not you think?) and that they were produced only a few, because it is dedicated to luxury homes.
As always, we will wait a few hours to give you the solution. Just wanted to recommend you not you get links in the comments to leave everyone else play guess what subject is that we are teaching today.
This time it was difficult but there has been a success: is, in effect, a swimming pool with a very suggestive ways slide. This slide is the shot and is so exclusive that only have manufactured three. The truth is that to me seems so beautiful it could even go for a sculpture garden.
