Tokyo, Japan-based photographer Shinichi Higashi takes long exposures to exciting new heights with his series Graffiti of Speed/Mirror Symmetry. While his colorful light trails seem incredibly futuristic set against Japan's modern architecture, it's the masterful merging of two identical images that makes this series so compelling.
While it's not immediately clear that Higashi has flipped a photo and then merged it, after a few seconds, you start to notice the small details, like the exact placement of the buildings or the rushing cars.
Also make sure to check out his set Tokyo Nocturne to see some bright and colorful photos of Tokyo at night. (Especially love this panning night train shot.)
