Saw a great astronomy/SETI themed video years ago that showed the Milky Way spiral and the Solar System's approx. position in it, and then started magnifying and closing in on our position. Eventually a tiny blue bubble became visible. That bubble represented the volume of space that had Earth's radio transmissions in it -- with a radius of about 200 light-years.
Very humbling. It put all the talk of communications to/from extraterrestrials into perspective. It also was funny to think that the stuff at the outer edges of the bubble was largely Morse Code, then some voices, and then I Love Lucy.
