My ART4FREEDOM is about how we are not free due to the the fact that politicians are only puppets, who do not care about our fate, therefore, they pretend that they cannot see or hear anything. They are often unable to tell us everything because they are observed and controlled by people at an even higher social level (in this case, in the background on the wallpaper, the skull represents just those people, who pull the strings and decide what to say to the public, as politicians just perform their tasks).
On the higher shelf, you can see some of the other puppets parts, which tells us that we are unable to change anything because new politicians will come in to replace those we have dumped with the same orders. They are only dressed differently or painted with different paint. Time to break the cycle and to break free. IAM4FREEDOM!
