Statue of Franz Kafka
It will surely surprise you the first time you see it. The day is more impressive, especially with sunlight, but at night with less movement around it and more distinctive lighting you will better understand its construction and operation. It is a statue - a head that changes shapes every few seconds. In theory, it is a work of art in constant motion, and it is supposed to be inspired directly by the work of the great writer (whose work leaves you different impressions each time depending on your own particular emotional and mental charge).
