I love those, and to be more honest, I love that someone is making those.
I view it the same as high fashion anyway, like the clothes on a catwalk at a fashion show are not meant for general use, they are there to show ideas and directions as to the way fashions are going, they are there for the purpose of art itself. And Jens basses are the same.
Although I would love one, I would look stupid playing it because I don't look good enough to pull it off, I am not the right model for the fashion
