This is amazing: http://primaxstudio.com/stuff/scale_of_universe/. After it loads, move the gray-square-button-slider under the picture to the left to see smaller, and to the right to see larger.
Looking at something like this really makes me appreciate how vast everything is, also puts into perspective how minor my problems and worries are. A teeny blip in the grand scheme of things. How lucky we are, with everything out in the universe (or multiverse) to have things in our world that are so pleasant, like music.
Speaking of music, careful, there’s music on the site! It’s not loud or annoying, but be aware in case you are at work and decide to peek.
