Artist uses optical tricks to create 'moving' murals

會跟你走的壁畫
這篇蠻有意思，臺灣海生館就有這樣的一面牆。
Rufus B. Seder是全世界唯一的藝術家擁有這樣特別的技巧。

Artist Rufus B. Seder calls these "movies for a wall" Lifetiles. The Massachusetts artist invented the Lifetiles medium and is the only artist in the world using it. He has more than 30 Lifetiles installations around the globe.
At the Taiwan Aquarium, dolphins swim on the wall alongside awestruck children.
Lifetiles don't use electricity, moving parts or tricky lighting -- just an elaborate and painstaking process done out of Seder's Eye Think Inc. studio near Boston.
"I love to watch people react to the work. They don't expect a wall to move," he said. "They'll be walking down the hallway in a museum and walking outdoors through a zoo ... and suddenly they realize, 'Those dolphins are starting to move next to me! How is that possible?' "
