This parametric design video shows Aperactive (interactive aperture), by Hunter Ruthrauff,  an interactive panel that opens based on user proximity. Its ability to be both opaque and transparent at the user’s discretion opens the doors to new possibilities to the relationship shared between private and public spaces. The idea is that this one panel is repeated as a pattern across a large wall so that as the user passes by each opens to reveal the space on the opposing side. In this way attention from the space within is shifted toward the direction of the catalyst and the catalyst becomes aware of activities being performed by the users inside.
