Is this what you imagine?

```

import gis

gis.renderGlobe()

```

the actual tiling logic, data storage requirements, performant rendering in something like a shitty 1990s browser... I don't think you have an appreciation for the difficulty of bootstrapping this ex nihilo.

Well, the article (more or less) says that it ran on an SGI workstation (some photos are available here: https://artcom.de/en/?project=terravision), of course it would have been impossible in a 1990s browser. What I actually wanted to say was that, while the technical feat of programming something like this in the nineties is certainly something to be proud of, I still think that the basic idea of zooming in from orbit to a certain section of the globe is too obvious to be patentable - and from a purely mathematical point of view (ignoring things like levels of detail of 3D models, memory limitations, the actual 3D programming etc.) the signature zooming-in animation from Google Earth (which apparently was also present in Terravision) is not that complicated to implement either.
