As we look at the CMB, we can see in our observations Doppler shifts that come from our motion around the Sun. We can also see our motion around the Milky Way. We can also see our galaxy’s motion in the local group. And, we can also see our local group’s motion as it gets pulled (and not pulled) by the gravity of stuff (and lack of stuff) around us. (A story on voids not pulling can be found in this post). [...] [...] So, here we are on the planet Earth.

Have fun shwag hunting! M81 was on my desktop this morning thanks to APOD,it was cool to read your subsequent interpretation. Have fun shwag hunting!
