Whoa that’s really cool! Also are you using some kind of IP to location? Was impressed you got my city right without needing location access

Edit: also super impressed by how fast the “shadow layers” are calculated. I’m in Switzerland and people here will love this ... knowing exactly when you’ll get sun in a valley is super useful. This might be something you could sell to people like search.ch - they could combine with the weather at meteo.search.ch - if you want an introduction say the word
