@wastingtimewithforums: The first link points to a desktop app and an online flash gallery that, after 10 years as you say, contains 200 models. Have you seen some models in the chrome site? just an example
I don't understand your second link.
But I do see your point. Almost anyone can make this. And you even don't need a 3d api to do it. One could do this with the canvas tag, although it will be kinda verbose compared to a real 3d version. Since IE will not support webgl (not now at least ), I wonder why Microsoft or its community doesn't accept the challenge and create something like this.
