How can I make a model loop a animation?

Like, a model (I'll name it 'Person') that's basically a normal ROBLOX, but in this case I want it to loop an animation, so people can see it's animation be done non-stop. Sort've like a gallery; putting the animation on display.

You may add a "while" like this:

while true do
	--Animation
	wait()
end

while true do wait() --ANIMATION SCrIPT end
