With services like email and social media, Amazon and Apple Pay, health, diet and even sleep-tracking, technology is pushing ever deeper into our lives.

Russian-born Danja Vasiliev and New Zealander Julian Oliver are part of a growing movement of coders and hackers who use their skills to create questioning and humorous digital art.
