Unlike optical illusions that are limited to paper, the works at the exhibition are real models, created using trigonometric formulas. A circle from one angle can turn into a series of interlocking squares when viewed from another angle.
The mirror placed next to the fish only reflects the skeleton. Some designs, only about 8cm in size, create an overwhelming effect, captivating even the most discerning eyes, whether observed from far or near.


Normally, the eyes are the most reliable and authentic witnesses thanks to their three-dimensional vision function. "Refuting" this belief in a humorous way, Professor Sugihara Kokichi took advantage of the "blind spot" of vision, creating seemingly impossible phenomena, giving viewers an interesting experience and contemplation on big philosophical questions.
In addition, his discoveries also stimulate scientific thinking, revealing the beauty and connection between mathematics, art and human feelings.

Since the 2000s, Professor Sugihara Kokichi has begun to explore these interesting visual phenomena and has participated in exhibitions in Japan and many places around the world . His works have been broadcast on many famous Japanese TV shows such as NHK's "DESIGN TALK plus" and the famous music group Arashi's "Arashi ni Shiyagare", and have been widely received by the public.
In addition, Professor Sugihara Kokichi's works are also displayed at many of the world's leading science and art museums, including the National Palace Museum in Taiwan (China).
The exhibition, which runs until August 24, helps Vietnamese audiences access a rare style that reaches sophistication in both mathematical calculation and artistic creation.
Author Sugihara Kokichi graduated with a Master's degree in engineering from the University of Tokyo in 1973, and then worked at various places such as the Institute of General Electronic Engineering, Nagoya University,
or Tokyo University before transferring to work at the University
Meiji 2009.
Since April 2019, he has been a Distinguished Professor Emeritus at the Institute for Advanced Mathematics Research at Meiji University. His major is Engineering Mathematics. While researching and developing robot eyes, he discovered techniques for creating realistic models of optical illusions and expanded his research to the field of optical illusions. He has created many seemingly absurd objects and is currently working as an Opt Art model artist.
Having won the Grand Prize 4 times and the Runner-up Prize 2 times at the International Illusion Competition, his optical illusion works have been exhibited at many science centers and museums, most notably a special exhibition lasting 1 year and 8 months from September 2018 to May 2020 at the National Palace Museum in Taiwan (China).
