There were two things which spammed through my head in the last days, concerning graphics or effects which may be nice. 
At first, as the subject tells you, the idea of bluring distant objects a little bit appeared nice to me. I guess its nothing very spectacular, as there are some games which already have something like that (Am I right here? Im not sure about that...)
Another thing I thought about was refracting things, as the Warpzone shader "wavy" does it. The thing I thought of was to make the mapper able to place a "trigger_heat" (or smth like that) at a place he wants which could probably be hot, as the area above lava for example.
If a player looks into/through this triggered area, he will see the objects behind/in this trigger refracted a bit. (I guess this is controlled by "dp_refract")
Im not sure if this things are realiseable, tell your thoughts
