Abstraction

One of the most amazing things I’ve ever seen is a demo of Photosynth done by Blaise Aguera y Arcas at TED 2007. Photosynth is a kind of sophisticated web robot that can find images (e.g. by scouring sites like Flickr), automatically determine which images are of the same object, and knit those related images together into an amazing mosaic through which users can navigate.

It’s impossible to really understand how incredible this technology is by reading about it. Take a look at the demo for yourself, and visit the Photosynth site.

What really caught my attention, beyond the technology itself, is the social networking implications for Photosynth. It’s enables one to look at an object (say, Notre Dame, as in the TED demo) through the eyes of thousands of people simultaneously; it potentially represents our collective view of the world. Amazing.
