Book Dominoes

This is absolutely nifty. I used to love putting together domino chains as a kid, but never even dreamed of doing something on this grand a scale. Just imagine an "oops" and bumping a book at the wrong moment during setup.

And then there's the clean up. I'm glad I wasn't involved with that. Either way, it's an ingenious and fun way to attract attention to the library - and I'm sure someone's going to try and beat their record one of these days too.
