To set randomly the clips in the texture maps you can use a random function to change the index of the clip.

A quick test (you will need to change the image source name)  :

var cGrids = ActiveSceneRoot.FindChildren("grid*");

oEnum = new Enumerator( cGrids ) ;
for (;!oEnum.atEnd();oEnum.moveNext() )
{
	var oGrid = oEnum.item() ;
	var rdm = Math.random();
	var index = randomClipIndex(rdm);

	SetValue(oGrid+".Texture_Map.ImageClipName", "Clips.seq__0__9_1__tga"+index , null);
}


function randomClipIndex(rdm)
{
	var index = 1 ;

	if(rdm < 0.1){
		return index ;
	}
	if(rdm < 0.2){
		index = 2;
		return index ;
	}
	if(rdm < 0.4){
		index = 3;
		return index ;
	}
	if(rdm < 0.6){
		index = 4;
		return index ;
	}
	if(rdm < 0.8){
		index = 5;
		return index ;
	}
	if(rdm > 0.8){
		index = 6;
		return index ;
	}
}


I'm sure there is a better way to do the random function but it gives the idea.
