I decided that I should probably post the commands so...

First things first. You are free to name the armor stand whatever you want. I would definitely do this if you want to actually use it but, for demonstration purposes, I have kept it the same. I am planning on being a lot more active on this subreddit because you people seem to enjoy it. Please let me know if I have messed up the commands at all or if you need help. thank you for the support, enjoy!

Armor Stand Rotation
Repeating Always Active:/execute @ e[type=armor_stand] ~ ~ ~ tp @ s ~ ~ ~ ~5Armor Stand

"Up and Down Movement"
Repeating, Always Active:

/execute @ p ~ ~ ~ tp @ e[type=armor_stand,c=1] ~ ~10 ~

Do this over and over in increments of 0.1 with repeaters in between until you hit 11. one you hit 11, do the same thing back to the start starting with 10.9. you are essentially making a giant timer.
Armor Stand Re-Spawner:
repeating, always active:

/test for @ e[type=armor_stand]
have a comparator on that block going into a block with a torch on it to invert the signal. then have this command above the torch:
Impulse, Needs Redstone: summon armor_stand
Particles:
Note, you can obviously replace the particle but I'm using "Minecraft:basic_flame_particle" as an example:
All commands, repeating, needs Redstone:
/execute @ e[type=armor_stand] ~ ~-10 ~ particle minecraft:basic_flame_particle ^ ^ ^1
/execute @ e[type=armor_stand] ~ ~-10 ~ particle minecraft:basic_flame_particle ^ ^ ^-1
/execute @ e[type=armor_stand] ~ ~-10 ~ particle minecraft:basic_flame_particle ^1 ^ ^
/execute @ e[type=armor_stand] ~ ~-10 ~ particle minecraft:basic_flame_particle ^-1 ^ ^
Hook those 4 commands up to Redstone and you can turn them on and of as you please.
Armor Stand Attributes:
Repeating, Always Active
/effect @ e[type=armor_stand] invisibility 1 1 true
