That's funny I saw that picture in the add and wondered the same thing myself. I saved the picture and was also going to ask the community who makes and sells them. I wouldn't be surprised if there was a lot of people interested in buying a set of them.

I was wondering the same. For some reason I'm thinking maybe Autoform.
