I was just wondering, considering the extreme temperatures that the Mojave Desert gets, it'd be really cool if New Vegas had some kind of heat haze/ripple (or whatever you call it) on roads and on things like metal roofs, like you see on hot days. I'm not sure if I'd be up to do it, but it's something that I think would be pretty awesome.

So, is it at all possible?
