Is it possible to automatically create instances? (especially image labels)

My goal is to create many particles on the screen, quickly and easily, and give them tasks (through events?). Imagine a button that sparkles whenever there's a 50% off deal, or snow particles on the gui that each move differently and have a different appearance. I'd love to do something like this:

for i = 1, 20 do
    i = Instance.new("ImageLabel")
    -- etc., etc.
    -- events which cause each instance to move differently
end

Is something like this possible? Or would I have to add every instance separately, give them unique names, and repeat the script for every instance?
