Nice work – product idea: find patios that are not in shade on a given day / at a given hour.
Bet you could even charge a penny for a feature like this.

#32This is really cool! It might come in handy when house or property hunting. Here is another, similar tool I have found helpful for gardening. https://www.suncalc.org/

#33That's a very cool implementation, I also like the idea of replaying GPX tracks this way!
Some time ago I made an app (Sun Locator) that has a similar feature (see here for a short demo: http://www.sunlocator.com/sunlocatorwebsite2_files/topo.gif). But your approach is definitely more elegant.

#34super awesome! I have plenty of fun playing with this.
* Is there a way to deactivate daylight saving time switches / locale-specific time and just use global UTC time? Because when I drag the "day-of-the-year" slider, at the end of March the rendering jumps for the switch from CET to CEST, and jumps at the end of October for the switch from CEST to CET - at least for my locale.
* Sunsets and sunrises are the most spectacular, just as in real life. Maybe one idea is to allow for a third slider controlling the "second of a minute" ... or providing an optional "time stretching"/"slow motion" dragging behavior the closer the current position of the "minute-of-the-day" slider gets to the moment of sunset/sunrise.

#36It would be need to see an "average cumulative annual sunlight" version of this (even in 2D).

#37Why on earth is the view oriented with SW up?
I chose this specific angle for aesthetic reasons but also to convey that the map could be rotated and tilted.

I forget the adage used on HN, but something along the lines of "People are more willing to pay to avoid pain than to gain pleasure". A tool to prevent sun burn or skin cancer seems more promising.
The shade layer is pluggable into any mapping application if you want to prove HN wrong [1]

Wow, that gif looks very similar to shademap. I don't have an android phone. Any reason you didn't release for iOS?
I really like the PowerPoint vibes in your intro video. Might look into doing the same.

#40This was neat.
I spent 3 years in Keflavik, Iceland in the 90's when I was a kid and my dad was in the Navy. I remember winter getting only a few hours of daylight where the sun would merely peek over the horizon for part of the afternoon. Looking at Iceland through this map, I was able to tell that some parts have hills to their south and during winter, they'll never leave the shadows.
Of course, go just a little more North, and during the summer, the sun never sets. It just circles the horizon.
