In 2009, I led a day camp for teenagers at the Canadian Centre for Architecture called 'Slow Teen.' One of the highlights of a very rich (and fun!) week together was when we turned one of rooms of the museum into a camera obscura. The teenagers entered in silence and (without our having to instruct them) they stayed in that silence for the hour we were there. The peace was palpable, mesmerizing... and nobody wanted to leave that space.
For anyone interested, I wrote a little about the experiences here:
