This is a collection of some of my work on the web.
Two tools for cryptanalysis of classical ciphers:
Building Walls Rationally: I wrote this puzzle to highlight on some of the surprising mathematical "coincidences" of the musical scale. My solution pages attempt to create a visual representation of musical intervals using the standard 12-tone scale, a 7-tone scale, and a 5-tone scale.
Ordering in Circles: This puzzle was inspired by a remarkable mathematical pattern I learned about at an exhibit in the British Museum.
