How to continually Instance.new() a camera to a specific block, every .5 seconds?

He's some example code that I'm working on. However, please don't only pay attention to the code. If you have your own idea, please share it.

-- Either put this in a seat, if it can only be used in a seat, or do your own thing with it.

function waitForChild(parent, childName)
	while true do
		local child = parent:findFirstChild(childName)
		if child then
			return child
		end
		parent.ChildAdded:wait()
	end
end

-- If you find any problems with this script, please message me (Daviidi), and I will try to fix them. :-)

You could Interpolate the camera as you insert a new part.

while true do
local part = Instance.new("Part",workspace) -- create a  part
Camera = workspace.CurrentCamera -- reference the players camera
Camera.CameraType = "Scriptable" -- make it "scriptable" or "editable"
Camera.CameraSubject = part -- set the subject  to the part
Camera:Interpolate(CFrame.new(part.Position + Vector3.new(-5, 5, 0), part.Position), part.CFrame, 0.5) -- move the camera nicely
wait(0.5) -- wait
part:Destroy() -- destroy it 
end
