photosynth + seadragon

this video is a truly amazing demo of two new apps (environments?) from microsoft live labs. photosynth is described like so:

"takes a large collection of photos of a place or an object, analyzes them for similarities, and displays them in a reconstructed three-dimensional space."

seadragon is a powerful browsing tool and wants to do the following:

"change the way we use screens, from wall-sized displays to mobile devices, so that visual information can be smoothly browsed regardless of the amount of data involved or the bandwidth of the network"

one caveat... there are lots of bmw ads in the video.
