Fuji Sun

I wanted to know if, when and where you could see the sun setting right on the peak of Mount Fuji. So I worked with Claude Code to build a Fuji Sun simulator.

You get to see the cone where you can see Mt Fuji, a slider to change the day of the year and also the time of the day to simulate what you would see using real terrain data and building data.

And for any spot that can see Mt Fuji and the sunset, it will calculate the optimal day for you to see it.
