Indeed, Noah's project was a direct inspiration for us, and we tried to clearly credit it.
We love that people are enjoying this so much, so we're also grateful to Simon Willison for reviving attention on the original project, and Zi Chong Kao, whose SQL tutorial site showed us the possibility of mounting the whole thing in a browser page.
(I'm the person who guided the Knight Lab students' original work and ported it to the web hosted version at mystery.knightlab.com)
And really, the most valuable piece, IMO, are the SQL web components, from SelectStarSQL, which are CC0 public domain.
