The ZWERM Tree became a popular hangout, for some players even a symbol of togetherness. Players passed by the Tree for an occasional 'single check-in' on their way to work or an errand, or met with their team for 'combo check-in'. Team placed posters on the Tree to invite other to come at a particular moment.
Although we designed the Sparrows for public interaction, private interactions proved a powerful amplifier of the social effects.
The Sparrows are interactive interventions attached to the window panes of residential houses. The inhabitants of these houses, volunteers we call 'Sparrow hosts', at times personally interacted with the objects, evoking playful interactions between the Sparrow host and the passersby. One player described to have experienced an “exciting yet invisible interaction” with a Sparrow host who seems to “enjoy making contact by echo-whistling”. So although we designed the Sparrows for public interaction, private interactions proved a powerful amplifier of the social effects. However, one Sparrow host received a written message in her mailbox calling her a cheater, signed with “the ZWERM inspection”. In future versions of ZWERM we will carefully consider interactions that mix public and private contexts.
