Since August 11, 2006 each daily haiku in the Masago blog has been linked with the previous day's haiku. This was in commemoration of reaching haiku #747 (a la Boeing 747). Each two subsequent haiku from then on has been linked in a renku-like fashion. The series has now been extended for an entire year (2006-08-11 to 2007-08-10; 747-1112). There is also plans of compiling and editing the project into a book.
The entire series of linked haiku in the project, including notes and link information, is archived here:

An index of Links use in the project:

Each haiku is posted with notes (in the comments section) about how it was inspired and/or remarks on background information of interest.
