Sketches

ermm here got two sketches, but same idea, any references? ermm my idea is putting two photos of tornadoes, one is smaller/weaker which recorded the current year(2008) , and another is stronger and bigger and is recorded the year(maybe 2100) and put a question there :"which one do you prefer?" with big font size and below will write "you can stop global warming" and put my symbol there.

REFERENCES of the idea

I got the idea of stacking of photos from this, photobucket slide show

and a little reference to this image
