Same here, after I wrote my comment, my next thought was what ways there could be enabled to have similar content on Wikimedia projects. The rules around Wikipedia projects (encyclopedic content, an article content narrated along an axis, as in meters here) and moderation are the hurdles from my POV. But then again, maybe it's simpler/better to have folks taking free content, putting it in a narration on their sites and linking back to Wikipedia as part of distributed Web.

Wikimedia projects are not limited to strictly encyclopedic stuff. A visualization about the deep sea could easily be allowed on Wikiversity, which is intended for miscellaneous educational material that doesn't easily find its way elsewhere. The biggest obstacle would be technical.
