Yeah, for some weird reason people tend to be asleep after midnight ;)

Well, using plunger to do this would be one idea, Erik suggested using a real
3D engine to do the job instead, like Ogre or even the Ember client directly.

I'm not convinced yet. There's going to be a ton of issues with brain-dead 3D
drivers on top of the usual issue with braindead browsers. Besides. I don't
even have 3D drivers installed on all the systems I use. And I'd be concerned
about this being dog slow on, say, a netbook.

That certainly was the idea. Wombat will actually look for thumbnails in a
specific directory and doesn't care too much _how_ the thumbnails get in
there in the first place.

Not at all, I'm glad you brought this up. It's always good when more than just
one person think about features.
