China possesses hundreds of man-made wonders that stagger the Western visitor…and a few wonders that fall a bit short. The Shanghai Tourism Tunnel is one of the latter. Connecting two popular visitor sights in Shanghai — the Bund and the Pearl Tower — with a tunnel under the Huangpu River, the light show along the mini-railway is a little underwhelming…until you see it through long exposures in a camera, that is. There, the lights and lines jump out at you in a psychedelic riot. It takes some experimenting to get the technique just right, and at 50 RMB a trip you want to catch on quickly. I gave it my best shot, and the results remind me of tie-dyed fabric.
