I don't know anyone who's done this, but this looks amazing! You know the plywood sheets that are under your carpet or tile? Well that's wood, not smooth oak veneered plywood, but with the right treatment it looks good in a very special way.
The site I link to below has a ton of information about how somebody accented his plywood subfloor in several different ways to create beautiful flooring out of the plywood in homes that is usually covered with carpet or other treatments. I really like what he has to show us. Maybe you would too!
