do curved seat tubes have curved seat posts?

[Philphine]

i think it's basman and nirve that have the curved seat tubes? is the seat post curved to match? is that possible? has anyone tried to do it themselves with any success?

i've had a bike idea rattling around in my head for over a year and it just became somewhat clearer. being able to make a curved seat tube with matching post might make the idea a little more possible. thanks.

I assume they just have a real short seat post that doesn't go into the curved part of the tube. If you look the seat post is a bit more complicated than just a post. It has another tube that extends onto the top bar. The seat adjustment is horizontally. I don't know any of this for fact as I've never seen one in person but it's just the way it appears to me from photos.
