This is an interesting concept. I also like the idea of projecting onto a ceiling of a room. It is always surprising the first time you try using an non-tracking telescope to see how fast the earth is turning. This gives you that without a telescope being necessary.

I block location requests, so it's just showing me the default location as Stonehenge. It would be interesting to allow the user to manually add location coords.

I _LOVE_ watching the moon transit my view port in my telescope. Love being reminded of this movement. The bigger planets are fun too.

shouldn't be hard. one difference is moving to a much higher/lower lat. to see the difference in angular speed. Where would you want to see?

was quicker to hardcode one, then add the feature

that's all sorts of awesome! thanks!

just as part of that hacker spirit, I tried changing the 32 to a different value in the url...:thinking-face:

lol. not a bad idea, but no, that didn't work. encoding latitude as a URL param... could save me from having to make a ui. it'd be something like ../zenith?lat=35.2N

		and if you wanted to adjust the timezone you could add &lon= again, admitted scope creep. I just hate that browsers allow for location data to be used. Sure, there's some cool/fun things that can be done like what you've done, but it's too easy to abuse it. Adding features like this that allow the user to set it, especially if they wanted to see what it looks like from a different location, would be less invasive while adding more features. Just so you know, even if I open gMaps, it guesses my location based on IP because I damn sure don't share with theGoog.

let me know if you'd like to beta test a new version. see my recent comment here.
