Barges crawl across our oceans like dark, anonymous sea monsters, hiding their contents behind mammoth walls. From a distance, we can only wonder what's contained inside, making its way from one land mass to another. Meanwhile, the birds -- and perhaps eagle-eyed plane passengers -- have a clear line of sight into the uncovered watercrafts.
Hungarian photographer Gyula Sopronyi must have been envious of the birds' views, or just plain curious as to what lies behind the barges' walls. His anxiety-inducing photographers peer inside the slow-moving boats, capturing the mesmerizing loads of people and objects that dwell upon their decks.
