After playing with photosynth for a few days, I have decided it is something I can do without. The worst thing I found about it is the fact that it uses Active-X, and I just can't bring myself to activate this app on a permanent basis. It has been a major security hole since it's inception, and I can't understand MS still wanting it include it in their line up. I would rather use a flash slideshow that is not browser specific. I'll wait until someone develops a similar app for Linux. I would think CompizFusion should have something like this, in their 3D line.
