Cloud Face is a collection of cloud images that a computer algorithm mistakenly identified as human faces. The series was compiled by Korean artists Shinseungback Kimyonghun, who note that the mishap "is a result of the computer's vision error, but [clouds] often look like faces to human eyes, too."
And if that wasn't fascinating enough, these photographs are from another project called Cat or Human, in which human faces were mistaken for those belonging to cats, and vice versa. You couldn't make this stuff up. Visit Shinseungback Kimyonghun's website, here, for more.
Happy cloud (and cat) gazing.
