Gianni A. Sarcone (born March 20, 1962) is a visual artist and an author of columns and articles for newspapers and magazines featuring visual puzzles and mathematical brain teasers. He is a contributing editor to 'Focus Junior'[1] (Italy), 'Rivista Magia' (Italy), 'Alice & Bob / Bocconi University' (Italy), 'Brain Games' (USA), and 'Tangente Magazine'[2] (France). Sarcone is also a designer and a researcher with more than thirty years of experience in the fields of visual creativity, recreational mathematics and educational games.

Visual Research

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 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 in the top 10 best optical illusions respectively in the 2011 and 2014 "Best Illusion of the Year Contests". Amongst other notable projects, he created and designed an “hypnoptical” [7] visual illusion that was used in the logo and institutional signage of 2014 Grec Festival of Barcelona,[8] a cultural event of importance that features avant-garde musical, dance and theater performances.

Educational Project

G. Sarcone has written and published several educational textbooks and illustrated books[9] in English, French and Italian on brain training and on the mechanism of vision. He is the founder of Archimedes-lab.org[10] a consulting network of experts specializing in improving and developing creativity - for which he has been commended with a long list of accolades and awards, including the Scientific American 2003 Sci/Tech Web Award[11] in MATHEMATICS and received recognition[12] in the U.S.A. from: CNN Headline News, National Council of Teachers of Mathematics (NCTM), and NewScientist.com.[13]

Media and Broadcasting

Some of Sarcone’s artworks such as The Other Face of Paris[14] or Flashing Star[15] have gone viral on the Internet. His works were also presented in several national and international television programs, including 'Rai 3' Italy, 'RTL 9 Channel' France, 'TSR 1 Channel' Switzerland, and in the following TV series:
