Mind Power Mystery Head is a highly detailed head done with the mesh tool and perfectly scalable. Very nice for mind power concepts. Under CC 3.0 Attribution.
Many people are puzzled by the word 'fracking' so I've tried to explain it in very simple terms, avoiding technical terms and jargon. This is a controversial technology but I've tried hard to present both sides of the picture, without reference to my own personal opinions. The result is a mini-presentation including a graphic and explanatory panels - rather like a poster.
I was watching those live streams of the "Occupy Wallstreet" protests in the USA, and I was moved by their passion. Somehow that influenced this "poster" about the power of people. Power to the people! :)
