Cardboard homebrew irising mechanism

More scenes from a book-tour: Boing Boing reader Jason Baker saw this morning's post on the homebrew irising peephole mechanism, so he banged up this awesome facsimile out of cardboard and hot glue and fishing line and pushpins and brought it to today's signing at Flyleaf Books in Chapel Hill, NC (thanks to all the awesome folks who turned out!).

Tomorrow, I head to NYC: Books of Wonder (May 26, 6PM); Brooklyn's Powerhouse Books (May 27, 7:30); and McNally Jackson (May 28, 7PM). The tour wraps in Toronto on June 4 with an event at the Merril Collection at 7PM. (

Reminder: There's plenty of libraries and schools and such that are hoping you'll donate a copy of For the Win to them!
