Techniques like long-exposure photography give us new insights into time and motion, distilling movements that occur over several seconds or hours into a single image. The pictures don’t really show us anything we’re not seeing in the first place - we could sit on a hilltop for a few hours and watch all those tail lights drive by - but seeing that activity in aggregate is something totally different. 'Transits', a one-hour, five-minute video German artist Ursula Damm shows vehicular and pedestrian traffic in Basel, Switzerland. It has a similar time-warping effect, but instead of achieving it with clever photography or digital effects, it relies on hand-crafted code to generate the stunning visual. In one sense it’s traffic, but in another, we’re seeing a beautiful product of an intentional feedback loop.
