Act on CO2

This is a pretty cool advert from 'act on CO2', we think its a picture of a industrial facility with smoke coming out of it, but by the end of the advert we see its actually a car exhaust with the background being a lady's dress and a bush!
I got really confused at first and started to quess what it was, but whats nice about it is that you can get to totally different scenes be changing the angle of a camera and getting closer or further back from the subject.
