Presuming you mean like an overlay that is animated in real time...over the top of your basic gameplay...
There is a example capx in construct 2 in your examples that illustrates an old TV Look...id start with that and add color transparencies and or alter the fx to get what look you need.
There are all kinds of FX you can make..for example Heat Haze and fullscreen underwater FX ...
just play around with semi transparent layers with WEB GL settings.
hope that helps somehow
