Wow, the topographic print is great. Although the technology is already quite old, I still get shudders somehow when looking at mountains and valleys in Google Maps. Creating little relief maps of the world around us would be awesome. That used to be something that public offices would showcase in their entrance, but it was a huge individual effort to create them. Today you could feed OSM data into a 3d printer, very nice.

Even at the size of the Churchill globe mentioned in the article, Mt Everest would still be less than a millimetre above sea level. So I don't think the mountain ranges would be very noticeable.

Hmm, I guess there's a point there, since it only has 0.1 mm accuracy. I think it'd still look cool with satellite imagery though.
