Love this, what are you using as the terrain elevation data source? I don't think this is something available from Open Street Map and can't see any attribution.
Also (bug report) it seems to be a little buggy on Safari on MacOS when you zoom out, it gets quite glitchy.
I need to change the default attribution positioning because it's under the time slider but the terrain data is aggregated by Mapbox in their terrain dataset. The building data also comes from the Mapbox vector tiles but is sourced from OpenStreetMap data.
Sorry for the glitches. If you copy and paste your url here, I can see exactly the zoom/location/pitch/bearing you're looking at.
Minor detail, but it seems like while the height of buildings is somehow reflected, the `height=*` key is not. So the church tower in my town has has less shadow than the apartment building next to it.
