Sometimes this control item appears and you can orbit a point cloud (using Ctrl+click-n-drag). This is particularly nice to get a spatial feel for a site (e.g. Mayan ruins of Palenque, http://photosynth.net/view.aspx?cid=0c71b1c4-8113-4bc4-bf4d-71ec4d9c6749).

TIA.

You can also turn off the photos by pressing the 'p' key.  The synther automatically detects objects, and the viewer places halos there.  When the synther sees that you've taken a number of photos all pointing at the same thing, it calls it an object.  If you take a number of photos from the same place, it calls it a panorama.

Check out Fere's rubik's cube.  This is an excellent example of an object.  For a panorama, see crater lake.  Here are the links:

Photosynth looks for 3 or more images whose cameras' "look direction" are all pointing at the same point.  It puts a halo around every such point.  (There are a few other minimal requirements in the form of synthiness and complexity of the point cloud)

P.S. There's notification for comments on synthn, but not on forum posts. I guess they're workin on that, as the forum is rather new.

I would hope so.  It's rather hard trying to find responses to my posts.
