An artist by the name of Benjamin Verdonck has built a man-sized swallow nest and hung it on the side of the Weena Tower in Rotterdam, Holland (aka The Netherlands). From his perch high above the city, he is behaving like a bird and staring longingly at a giant ‘lost’ egg he has placed on the sidewalk below. Based on the reactions from the people in this video, I’d say they think Mr. Verdonck is just moments away from the cuckoo’s nest.
