Twinkling Stars

What would be the best way to have random twinkling stars? I tried using particles and i didn't like the effect.

Maybe place a star with a random position:

X: random(0, LayoutWidth)

Y: random(0, LayoutHeight)

and then change the opacity of the star every x seconds, so you get the illusion of its blinking.

That should work. I just couldn't think of how to do it.

Thanks

Give the stars the fade behaviour and have them fade in and out when created?

Thanks again, i did it the hard way at first.
