Explosion Heatwave Distortion (unity indie)
An article by 
Fullscreen heat/explosion distortion effect shader+script [View animated gif]
Info:
– No rendertextures used, works with unity indie, (but slower of course)
– Could be possible to have multiple heatwaves on screen.. (not tested yet)
– In the webplayer its bit slow moving, too strong effect (and looping) just to see it better..
Webplayer:
http://unitycoder.com/upload/demos/ExplosionHeatDistortUnityIndie/
References:
Normal map for the heatwave is from “Detonator framework” (asset store : https://www.assetstore.unity3d.com/#!/content/1?aid=1101lGti
*This package works nicely on 4.3.3, but requires PRO for the heatwave effect..)

interesting effects here, some shader code samples too, might work in unity with few modifications:
