These photographs were captured through what at least one group of awesome Germans are calling Light Art Performance Photography. Practically, all that means is long exposure photography capable of transforming a dot of light into a solid string when moved. The performance aspect is, presumably, that these photos are acted out in one continuous shot.
We've seen the same photographic phenomenon in Sprint commercials, or even in the recent Light Writer iPhone app. But the work we see here is exceptional—a stunning artistic statement with a remarkably analog sensibility. You can see lots more by following the link below.
