Gianni A. Sarcone (born March 20, 1962) is a visual artist and author who collaborates with educational publications, writing articles and columns on topics related to art, science, and mathematics education. He has contributed to several science magazines, including Focus Junior[1] (Italy), Query-CICAP (Italy), Rivista Magia (Italy), Alice & Bob / Bocconi University (Italy), Brain Games (USA), and Tangente[2] (France). Sarcone has over 30 years of experience as a designer and researcher in the areas of visual creativity, recreational mathematics and educational games.

Visual research

File:Sarcone Relative Size Illusions.jpg
Here are two relative size illusions described by Italian visual researcher Gianni A. Sarcone in 1997 and 2013. The first relative-size illusion called Sarcone's Crosses contradicts Ebbinghaus illusion (aka Titchener Circles, 1898) and Obonai square illusion (1954). Sarcone's cross illusion consists of a cross (the test shape) surrounded by sets of squares of distinct size (the inducing shapes). As shown in the diagram, the three blue crosses in fig. 1.a, 1.b and 1.c are exactly the same size; the one on the left (fig. 1.a), however, appears larger. The illusion works even when the small squares completely occlude the blue cross (see fig. 1.c). In conclusion, there isn't always correlation between the size of the surrounding shapes and the relative size perception of the test shape. In fig. 2.a and 2.b, by effect of assimilation, the diagonal red line within the large ellipse seems subjectively longer, but in fact the blue line is objectively the longest of both lines.[3]

Considered a leading authority on visual perception by academic institutions, Sarcone was invited to serve as a juror[4] at the Third Annual "Best Illusion of the Year Contest" held in Sarasota, Florida (USA). His optical illusion projects 'Mask of Love'[5] and 'Autokinetic Illusion'[6] were named among the top 10 best optical illusions in the 2011 and 2014 "Best Illusion of the Year Contests", respectively. In 2017, he placed third in the contest for his ‘Dynamic Müller-Lyer Illusion’. [7]

Amongst other notable projects, he created and designed an “hypnoptical”[8] visual illusion that was used in the logo and institutional signage of the 2014 Grec Festival of Barcelona,[9] a significant cultural event featuring avant-garde musical, dance, and theater performances.

His joint work, “Moona Lisa”, a mosaic of lunar images that, when viewed from a distance, forms the iconic portrait of Leonardo da Vinci's Mona Lisa, was featured as NASA’s Astronomy Picture of the Day (APOD) twice: on October 16, 2021,[10] and again on September 14, 2024,[11] in celebration of International Observe the Moon Night.

Since May 16, 2022, in honor of the International Day of Light established by UNESCO, the University of Florence (UniFi) has permanently hosted Sarcone's optical art works in the Department of Physics and Astronomy in Sesto Fiorentino. This exhibition, titled “Enlightening Mind”,[12] is freely accessible and organized by the Degree Course in Optics and Optometry.
