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..

References:
Normal map for the heatwave is from “Detonator framework” (asset store : https://www.assetstore.unity3d.com/#/content/1 *This package works nicely on 4.3.3, but requires PRO for the heatwave effect..)
