In case you're wondering, "Kugelblitz" is German for "ball lightning" (literally "spherical lightning")- probably refers to showing the "sphere" (the Earth) as fast as lightning?
Great ! I tried it on my apple M1Pro and it works fine :)
I would not put the grid at first lunching and I'd like that the earth keep spinning a bit when throwing it with the mouse !
Same, such a shame developers are going this route, e.g. Raycast 2 as well won't work on older MacOS versions. I don't plan on updating to the liquid thingy as long as I can on my laptops.
With the upcoming retirement of google earth (desktop), I'd also recommend looking into geolibre for this sort of thing. No it doesn't come by default with a nice full color photo mapped onto 3D terrain as google earth does, but for less technical users or those with less complex demands, it has a much lower learning curve/complexity than giving people a full QGIS setup with a bunch of back-end db connected.
Sadly, Kugelblitz is only available for Mac and is closed-source for now. And, of course, it's vibe-coded. He talks a little bit about his reasoning on his podcast (in German): https://logbuch-netzpolitik.de/lnp563-des-kaisers-neue-kleid...
As if Google Earth wasn’t smooth on a 2.0 GHz Pentium 4 in 2009
