I'm looking for a good effect to put on my spooky eyes. I have 8 total in 2 strings of 4. One string in the bushes to the left side of my house and one string on the right side. Trying to figure out a way to get a slow random blink. Got any good examples. I've been playing with single strand skips and twinkle but not getting what I think I need which would be more like a hidden monster blinking randomly.
