It's a great graphic, but it's "a little busy", isn't it !? Fortunately, if you click through to the source at the NASA Scientific Visualization Studio, they have various overlays and components that could be assembled into other visualizations. I dislike the rolling position angle, and I can't seem to find any variant with that eliminated. But the elements available could be converted easily enough, I suppose. :)
Here's the Moon at 10am UT on March 20 at the time of the equinox (just to pick a random well-defined time).
