Widener has an extraordinary ability to process numerical information, which has profoundly influenced his art.

His creations combine mathematics, history, and a fascination with time, with an obsession for numerical patterns and calendars, elements he uses to explore abstract concepts of history and the future.

Widener's work has an obsessive approach to time and numbers. His pieces often resemble riddles in which visual and mathematical representations are mixed, as if each drawing were a codification of historical or future events.
