I didn't even realize this was a topic until I stumbled across an article the other day about all the time and effort that societies put into the illusions of security. TSA is a great example of security theater, it is all a big show to keep everybody fearful, on edge, and accepting of state control and militarism.
Ubiquitous surveillance has rightly generated major concerns world wide. The new high technology that is a great boon to is also being used against humanity in many instances. The response to this is the subject of Cory Doctorow's new eBook Little Brother, freely downloadable.
Another piece of art that I came across was kind of delightful but upon reflection and review is a commentary on Security Theater.
I came across another thing that you might interest you as an artist exploring new forms of expression.
It is a UK band that assembled a music video by setting up and playing in front of various CCTV security cameras and then applying under the provisions of the Access to Information laws for copies of the recordings. They then stitched it all together into a rather nice piece of art, IMHO. Newspaper article describes the project.
Great song and an interesting commentary on Big Brother
