- Jesse Weisbeck has built this crossword puzzle to provide an enhanced, more intuitive user experience with javascript.
- Ash Kyd did bug fixes and added cool features (e.g. the "reveal a random letter" cheat).
- The Dod added rot13 (against accidental peeking) and an example puzzle that uses it (EFF's Xmas 2013 NSA puzzle).
Your turn :)
