Hi,
Reading the "2012-13 Plan", I see that multimedia is one the key activities for Mediawiki. So I was wondering if there was already any plan to integrate 3D model viewers, which would be for example very interesting for anatomy articles, or simply 3D maths objects.
MediaGoblin[1] show that we already all the free software stack to do that, however I don't have enough data to estimate development charges of that kind of features into Wikimedia.
