Launch Countdown "3, 2, 1, GO!"

A bold flat motion-graphics countdown on a plain solid electric blue background. The big white numbers "3", "2" and "1" appear one at a time in the center, each popping in slightly larger and then shrinking to its normal size, followed by the word "GO!" in yellow with a small burst of lines. Then it starts again from "3". Every number is centered, in the same font, and perfectly legible. Camera still.
