I've been using POV-Ray to simulate how curved the horizon appears at different
altitudes.

I chose to use POV-Ray rather than a standard modeller (e.g. Blender) as I can
actually get a perfect (Non-polygon) sphere that way.

It also comfortably handled the 2.15GB 86400x43200 pixel texture I used for the
detail! (Blender couldn't handle it!)

Nice!

Might be interesting to somehow highlight a few key altitudes, such as:

- altitude of Mt Everest
- altitude of typical intercontinental flights
- altitude at which space officially begins
- altitude of the ISS
- altitude of geostationary satellites
