I just Combined the motion Blur radial shader with the heat haze shade And I got it working!

It was really hard thoughhttp://www.youtube.com/watch?v=ssPe8dKOL7Y&feature=c4-overview&list=UUr0boUODFnZmY-PWnSyMokg
I always like to see someone have a breakthrough. It feels good. Enjoy that s*** xD Now if only I could get my problem worked out...
amazing job
