This is the beginning of my alien invasion scene. I'm using a single tri-color led which can essentially give me any color desired. I'm also using an Arduino to power it using PWM to give fade in and fade out effect. There is also an occasional strobe that flashes (which is just all colors RGB giving white). I've been playing around with all different colors and effects and there is no limit as to what I can make with a single LED, from welding, fire, lightning, strobes, etc.
Please see the full video on YT for full lighting effects:
