About the Cloud Gate
The Cloud Gate by Kapoor in Chicago is the most populair work by Kapoor. The gate is created for people to walk through and experience a different form of their surroundings. The Gate also provides a panoramic view over the city with a skyline that walks horizontally through the object. The reflective ability of the object does not only make the object nice to walk through but it also creates a never ending change of the object.
About Kapoor
Anish Kapoor, CBE RA (born 12 March 1954) is a British-Indian sculptor. Born in Bombay,[1][2] Kapoor has lived and worked in London since the early 1970s when he moved to study art, first at the Hornsey College of Art and later at the Chelsea School of Art and Design.
Kapoor attended the prestigious all-boys boarding school The Doon School in Dehradun, Uttarakhand, India. He is said to have “hated” his time at Doon. In 1971-1973, he travelled to Israel with one of his two brothers, initially living on a kibbutz. He began to study electrical engineering, but had trouble with mathematics and quit after six months. In Israel, he decided to become an artist. In 1973, he left for Britain to attend Hornsey College of Art and Chelsea School of Art and Design. There he found a role model in Paul Neagu, an artist who provided a meaning to what he was doing. Kapoor went on to teach at Wolverhampton Polytechnic in 1979 and in 1982 was Artist in Residence at the Walker Art Gallery, Liverpool. He has lived and worked in London since the early 1970s.

Platform and creator
The platform has been created by the people of Chicago the architects and engineers that have worked on the skyline of Chicago and America. The collection has been created by Kapoor as a result of his study on human behaviour in open areas.
What makes the collection
The collection could be created by the different circumstances reflecting in the Cloud Gate throughout the days, months or even years. The building has a never ending change of colouring, people and other objects and aspects that reflect in the gate.
The people and the building make the work of Kapoor. Because of the reflective ability of the Cloud Gate the people make a difference in the appearance of the object by standing in the reflective area. When the people walk through the gateway of Kapoor they experience a feeling of disturbance, a misleading interpretation of reality through transforming mirrors, some people actually got sick from walking through the gate.
This piece can be made into a collection by using photography or moving images of time and space evolving through time in the object.
Personal Reflection
Kapoor has made a lot of reflective objects in cities that have brought much people together in an interactive atmosphere. The way Kapoor knew how to make an object that does not especially need to be complex but bring a big audience to interaction is very impressive. The easy shape and material have a bigger impact then other object that can be much more complex. Maybe the simplicity makes it easier for the audience to understand and participate in the object.
