Chinsekikan means "hall of curious rocks." It's the name of a museum in Chichibu, Japan, that is full of rocks with markings or shapes that resemble faces.
According to the Sankei, the museum is currently run by Yoshiko Hayama, the wife of the original owner who passed away in 2010. But it was his rock collection that started it all. An avid collector, the late Shozo Hayama spent 50 years collecting rocks that looked like faces. His only requirement was that nature be the only artist.
There are currently so many rocks on display that some don’t even have names. So the owner occasionally invites visitors to name the rocks.
People tend to see faces in anything, and seeing so many rocks looking back at you all at one must be a unique experience. You can get a taste of that by seeing the photographs at Colossal. You'll recognize the one that looks like Elvis right off. -via John Walkenbach
