There is clearly no shortage of genius in RCA’s Innovation Design Engineering course – its current degree show is positively teeming with ingenious solutions to pressing sustainability, societal and technological hurdles. But sometimes it’s the lighthearted innovations, the little things that stoke human happiness that win us over most. Among his peers’ projects, Chin-Wei Liao’s Duo, a novel little camera that seizes upon the magic of social snapshots–and the selfie–that most cleverly captures the zeitgeist.

As with many a digital phenomenon, selfies are (hence the name) all-too-often awkward and anti-social, lonely duckfaces in the bathroom mirror. With Duo, however, the solo act becomes social: the camera breaks into two mini halves for sharing, each with a synchronised shutter, whose two resulting snaps then constitute two sides of the same image.

The design is an interesting play on a trend towards convivial objects we’ve seen in full-force recently. But unlike most, which tend heavily towards the analogue, the Duo as thoroughly digital object is unique and perhaps a harbinger of a new form of digital social. And with so many 21st century versions of the half-heart locket here on the feed lately–Nicholas Jaar’s Prism, Coke’s shareable can and the Global Sounds installation just to name a few–we should all be feeling pretty warm and fuzzy and full of love.
