The 2025 Sawyer Dialing Prize went to Simon Wheaton-Smith "for his Illustrating Shadows publications and his dedication to making dialing knowledge accessible to all". Simon received a cash prize, award certificate, and glass Spectra Sundial made by Artisan Industries.

You can find his inspirational sundial website at https://www.illustratingshadows.com/ where his website presents many types of sundials and multiple methods of creating them. If you need basic or advanced mathematics on sundials, the Appendices to Illustrating Shadows is just what you need. Wheaton-Smith's goal is to provide teaching aids and useful tools for making and using sundials. And there are a pot pourri of links to software programs, spreadsheets, and CAD scripts. In all, Illustrating Shadows contains 1,174 pages of sundialing knowledge made freely available to all.

Thank you Simon.
