Edgar Mueller, 2008. Festival of World Culture, Ireland.
It took five days and multiple assistants to accomplish the task, but German artist Edgar Mueller created what is most likely the largest scale street 3D optical illusion of it’s kind to ever be brought to fruition. The image is only viewable from one specific vantage point, othewise the overall effect is undetectable. Mueller has said that one of his favorite moments to witness is when an observer accidentally “runs into the picture”. I can imagine that in this particular example, that this visual collision would be quite a frightening and dynamic moment.
Here is a video of the five day process of creating The Crevasse:
