“Screen Time is a community clock connecting strangers through their mobile backgrounds. Participants are invited to take part by making a screenshot of their mobile device lock screen and submitting it to the allocated time slot. The submitted images are then compiled and presented, each being displayed for the single minute at which they were taken. The outcome is a clock that each minute reveals a glimpse into someone else’s life.”

“Other Orders is a tool for sorting text and tweets.

Recommendation engines like the ones powering the endless feeds on Twitter, Facebook and YouTube, are designed to maximize ad revenue, and therefore to keep you online for as long as possible. In doing so they promote the most reactionary content on their platforms. Yet, these recommendation systems are nothing more than sorting mechanisms.

Other Orders provides an alternate set of sorts, optimized for other outcomes.”
