How about this. Floorboards without the straight lines. I love it.
These are made in Finland using computer CAD/CAM by Bolewood
Modern life is so full of straight lines a wavy line brings a bit of nature into the home. This is the high tech way of doing it, I do it with a saw and by eye in the way threshing floors have been made for centuries. Great to see it coming to the mass market, I bet they will sell well, those clever Finns.
I first saw floors like this in the home of the fabulous American woodworker/sculptor Wharton Eshrick, if you don't know him I recommend the website. There is a good description of how threshing floors used to be made in Walter Rose's book "The Village Carpenter".
