From a distance, Kim Chang Young's "Sand Play" seems to defy the law of gravity.
Embedded into the tiled wall at the entrance of Ushigome-Kagurazaka Station is what at first glance appears to be a beach. The 10-meter-long, 2-meter-high work resembles a stretch of genuine sand, its smooth, damp surface scuffed and scratched here and there, perhaps by an idle passerby.
As you approach it, however, you think you have uncovered the trick. It's an ultra-real painting, or maybe a photograph. But there's still something urging you to touch the mounds of sand that have seemingly been swept up by human hands.
