About this product

When rotated, the color changes to reveal yet another pattern. The shape and design of this frame are ingenious. When the red and blue painted dokuraku are rotated, the colors blend together to create a beautiful purple gradation. When you spin the wind motif, it looks like a gentle breeze or a powerful whirlwind, depending on the speed at which you spin it. When the crescent moon is spun, a rainbow of seven colors appears. There is also a mysterious spinning top that looks like a three-dimensional pop-up of mixed colors. Find your favorite among the 12 types of dokugaku.

Included in this product set are white and black colored dokugaku. You can make a surprising scientific discovery with this one. Before you spin it, it is black and white, but when you spin it, you can see colorful colors on it! Moreover, the color you see is different for each person. This black-and-white spinning top uses an optical illusion called “primary color perception” to create a mysterious experience. Each person perceives the colors differently depending on the light, the speed of the spinning top, and the function of the eyes.

If you repeatedly blink your face close to the spinning dokuraku, the mixed colors appear to break up, and some dokuraku pictures appear to pop out three-dimensionally. Please enjoy the beautiful patterns.
