When nature meets interior design. Natural stone sinks give off a spa-like feel to any bathroom and you'll soon come to realize how much I love spa-like decors :). From Freshome.
Another piece where nature elements have been used to create something functional. These mushroom lamp sculptures are done by a very talented Japanese artist and are simply breathtaking. Use them as an art piece or as a small ambiant lamp or both! They unfortunately do not ship overseas due to the fragility of the item. When the day comes that I will be visiting Japan I definitely want to get myself one of these (I'll make sure they survive the ride back!)
Lighted branches also can add a nice touch to any indoor space.
