About the Author
Gianni A. Sarcone and Marie-Jo Waeber are co-founders of Archimedes’ Laboratory, an Italian-based training and consulting network of game designers. They invent, create, and develop interactive thinking games and optical illusions, as well as educational materials involving colors and shapes.
Sarcone and Waeber also regularly write columns for newspapers and magazines featuring visual puzzles and math brainteasers. Fervent puzzle enthusiasts, they frequently travel around Europe to give workshops and share their knowledge and ideas at cultural and educational events for both adults and children.
