Concentration Chamber Fake Book

The Concentration Chamber Fake Book appears to be a standard paperback novel, complete with embossed cover art and crisp pages. However, upon closer inspection, the book reveals itself to be a sophisticated distraction tool designed to help users feign focus during meetings and lectures. Its hollow contents are calibrated to radiate subtle vibrations at specific frequencies, inducing mild drowsiness and prompting natural nodding motions when opened to arbitrary page numbers.
