You're right, I should probably have posted the link to the live project instead of the blog post. I figured that the story of why I did it is interesting as well though.

I was more expecting to see the link of how you did it on HN. I mean I got there from the link you posted but as this is a technical crowd I'd have thought that was the more interesting thing.

As an aside, I'm very impressed that the Sun appears to dim during a solar eclipse (http://mgvez.github.io/jsorrery/?scenario=EarthMoon&planetSc...) but I'm surprised it isn't hidden completely - have I just got the timestamp wrong for the specific viewpoint you're using?

I hesitated when posting the article. Maybe I should have posted the technical one. I wrote them all in one piece, but split them afterwards for different crowds. The one I posted is the least technical one of all, but it's the entry point. My bad. The best scenario to see eclipses is the Inner Solar System, and put the scale to 1. Eclipses are very difficult to simulate, as the distances are so huge, you need to have incredibly precise positions to observe one. But it is still possible to see them, for example at http://mgvez.github.io/jsorrery/?scenario=InnerSolarSystem&d...

Having read the help text about the moon position I understand the problems. It's still so damn impressive though, I didn't mean to sound critical above :)
