Saw, the video now, A Stargate, very cool. I don't do coding myself so can't help you there. The other thread might be helpful for that.

In my method I am not sure you could get that lovely lock in sound per chevron that you have, more just one long sound effect for the entire thing. The sequence itself could be done in one animation if it isn't variable. The colour change module is more an all on at once thing so you would still need the animation to hide it and show it I think. It is one of the most complex things I have seen in KSP so if one of the coding experts in the other thread can help you then that is probably better for you. Otherwise I think 1 long animation that includes rotation, location and resize in the keyframes, using resize to bring the lit chevrons out of hiding under the skin on each chevron activation.
Good Luck.
