"Kochi-jo castle and Kinkaku"

When observed at close range, the image shows the Kochi-jo castle, while Kinkaku is observed if we see this image from a distance. For those who wear glasses, Kinkaku is always dominant when they take off the glasses. This image is a kind of hybrid image proposed by Oliva, Torralba and Schyns (2006).
