Librairie Formats, Montreal, March 2015 – As part of the Formats X series we were invited to invest the space of the bookstore, and in so doing brought our book-writing process to life with the participation of others: spatial contaminations (an interactive display of our research artefacts); treasure hunt (secret notes hidden inside a selection of research texts); detention (a time to do homework collectively), and other spontaneous (not to mention contagious) interventions.
