How to make modern art

1) Pick a political topic that people feeling passionate about (e.g., global warming)
2) Pick an iconic image for this
3) Create a replica of this image, but make it so that it is not ordinary (e.g., give it a different size or other quality)
4) Put it in a different setting

Voila! you have this: Pylon in Birmingham

If there is more to this than what I just described, I am missing something.
