Wonderball

I've been messing about with full 360 x 180 degree panoramics. When you map one of these photographs onto a sphere and walk inside it, it gives a good sense of being in a real space. The image distorts a little as you move around in the sphere, but your brain seems to be able to make adjustments quite easily, so I can imagine that you could map other objects within this space and you would get a reasonable sense of their position in relation to the projected panoramic. If you had a bunch of avatars inside this space, and each avatar had a rectangular cone object which projected out in the direction they were facing (the cone would correspond to the field of view of their camera), then everyone would be able to see what they were looking at. This would be very useful in group discussion about the location of the panoramic image that everyone was inside. It would also indicate when someone was looking you in the face, providing another valuable visual cue in the 3D virtual space. Browsers and whiteboards could also be placed within the sphere to facilitate the discussion.
I reckon all of this is do-able with Wonderland.
