Clone patterns, make circles/donuts/spheres, for testing farms or just messing around. Credit to xisumavoid for showing this for clearing large areas of land, though I don't know which video he showed it.

Something I forgot to mention, for the "teleport back to start" it detects whether an armor stand is farther than a certain distance, which is easy and works, but not precise. I would've rather used dx,dy,dz, but those are awkward. It should also be possible to use /execute (if|unless) block

Some example commands used:
Teleporting armor stands
/execute as @e[type=minecraft:armor_stand] at @s run tp ~ ~ ~8
Clone to armor stand position
/execute as @e[type=minecraft:armor_stand] at @s run clone 22 62 19 24 65 23 ~ ~ ~
Create armor stand with tag
/summon minecraft:armor_stand 31 59 35 {NoGravity:1,Tags:["lowestlevel"]}
Clone dependent on tag
/execute as @e[type=minecraft:armor_stand,tag=lowestlevel] at @s run clone 22 59 19 24 61 23 ~ ~-3 ~
Replace lever when armor stand a distance away
/execute as @e[type=minecraft:armor_stand,distance=60..,limit=1] run setblock 16 63 26 lever[face=floor] replace
Summon area effect cloud (use lower -age to last longer).
/summon minecraft:area_effect_cloud ~ ~ ~ {Age:-1000}
Create spheres at every armor stand
execute as @e[type=minecraft:armor_stand,tag=spherehere] at @s run execute as @e[type=minecraft:armor_stand,tag=Zdirection,distance=5..10] at @s run setblock ~ ~ ~ stone
