We were definitely surprised by the gusto with which the monks took to the challenge. Their observation were methodical, precise, and varied, even creative (for example, it was not uncommon for them to hold up the box to their ear to try and determine, from the sound of the mechanism, whether there were gears involved or not). They made very well-thought-out drawings and schematics of possible mechanisms, and then defended their ideas with each other with great vigor.
