Visual research
Considered a leading authority on visual perception by academic institutions, Sarcone was invited to serve as a juror at the Third Annual "Best Illusion of the Year Contest" held in Sarasota, Florida. His optical illusion projects 'Mask of Love' and 'Autokinetic Illusion' 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’.Amongst other notable projects, he created and designed an “hypnoptical” visual illusion that was used in the logo and institutional signage of the 2014 Grec Festival of Barcelona, 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 twice: on October 16, 2021, and again on September 14, 2024, 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 has permanently hosted Sarcone's optical art works in the Department of Physics and Astronomy in Sesto Fiorentino. This exhibition, titled “Enlightening Mind”, is freely accessible and organized by the Degree Course in Optics and Optometry.
Educational project

He is the founder of Archimedes-lab.org a consulting network of experts specializing in improving and enhancing creativity - for which he has been commended with a long list of accolades and awards, including the 2003 Scientific American Sci/Tech Web Award in Mathematics and received recognition in the US from: CNN Headline News, National Council of Teachers of Mathematics, and NewScientist.com.Notable inventions
Sarcone has developed a number of visual puzzles, games, and conceptual objects that combine elements of geometry, color, perception, and philosophical reflection, often grounded in mathematical principles.Quirinus – The Amazing Paradoxical Puzzle – A 16-piece geometric puzzle from the *Quadrix* series that presents a vanishing-area paradox: an additional square appears to fit within a completed shape without altering its perceived dimensions.TangraMagic Puzzle – A reimagined ten-piece tangram that introduces L-shaped elements and a small square to produce an optical illusion of area disappearance. The puzzle includes a 20-page illustrated booklet designed for educational and recreational use.Trama – A two-player abstract strategy game designed in the early 1990s. Played on a triangular board with black, white, and neutral gray pieces, the game introduces a shared neutral component that adds a layer of tactical depth.Architempo – The Hological Watch – A conceptual watch using a two-color pattern to visually represent the passage of time in an hourglass-like display. Conceived in the late 1980s, the design explores alternative ways of perceiving time through graphical interaction.Media and broadcasting
