Shot at Sunshine City in Ikebukuro, Tokyo. The stereoscopic pattern was drawn on the ground of the square in the shopping mall. And a kid was running around on the pattern-like ground.
Although it was level, the pattern developed the delusions that the floor was sterically-oriented. It looked like it had just gone to another world when I saw from the upstairs. The kid seemed to be able to have a place in disregard of the dimension. Maybe the young children have such ability indeed.
