Looking for a moving air shader

Hi all.
I'm looking for a shader/effect You can see f.e. in last C&C. When something is burning the air is moving/deforming. The same with plane's engines or shooting ray.
Looks like moving rain drops shader (where part of screen is deforming from Sylex3), but it's something different. It's attached to model not to camera (like in post process effect) so you can f.e. partly cover it up.
It's hard on static screens but look at sidewalk f.e., how it's deforming by ray's . ScreenShots

It is just some simple refraction

and accidently slin did a great heat haze shader!!!

Yeah... true... my mistake
But... where can I find codes? I've been looking here and wiki...
I only found slin's great demo (but graphical errors with 8600GT) looking the same as puppeteer's one. link
and glass (refraction) code.
Where can I find all together code? working one?
I'll be veeeery glad

You can find a refraction shader from oliver2s in the massive shader collection.
Look at the AU recource page, there is the collection.
