		interval : time in MS (secs * 1000) between transitions (does not include transition time! - do not set below 1000)
		fadeIncDelay : delay beween each "step" of a transition
		colorMap : (array) contains each stage of color, script will loop from colorMap[0] > length, so to speed effect remove every other state for example. to go to black uncomment lines.
		
	[future/recommended enhancments:
		should be made entirely reusable by pulling hardcoded "textlink" out of function into function arguments.]
