Perhaps most things about Earth wouldn't be MOTD-worthy, but our creation of EM energies of various frequencies modulated to contain highly-compressed information probably would, as would the particles generated by the LHC that probably don't happen much without intelligent design (in the form of us.)<p>An interesting thought occurs to me, though: wouldn't a black hole be the perfect way for a non-omniscient being to sample the universe? Because any information you encounter will become quantum-entangled to you in some way or another, you'll want to make sure that you aren't mucking up the samples taken with your presence—and what better way is there to ensure that than to have information probes that look and act like natural phenomena, and "disconnect" the source of any data they gather from the rest of the universe before working on it? It makes UFO abductions seem mightily small-scale.
