Heat wave effects

What I have done here is added a heatwave effect to the scenes to show how arid the place is without water. I did a test on a single frame for faster test results to see what it will look like. I followed this tutorial http://creativemac.digitalmedianet.com/articles/viewarticle.jsp?id=34773-2 to create the heatwave but changed it to suit the films look. It gives additional movement to the scene which will look appealing to the viewer.

I have tried uploading a video on the blog but the video seems to be too small to notice any difference.
