Want to see a real interesting one? Do a google image search for the Veno borderless handlebar.

From what I can tell (I don't read Japanese) it's actually a zero drop/reach carbon fiber drop bar...Came across it in my never-ending search for the perfect drop bar for a MTB. Apparently it's not sold stateside, but I'd love to try it out. The downside (based on the pics) is that you can't access levers from both the hoods and the hooks.
