I've been reading alot about wood grain in designs. I'm not sure it fits all different types of websites, although some people seem to be trying to make it fit. I don't like wood paneling in cars either though, so its probably just me.
Another one is retro/ivintage looking sites. I think they are super cute. I love the less is more approach and vintage makes it simpler since you probably don't want to edit them heavily. Its a very comforting look.
