Foursquare

Foursquare is the iPhone app that rewards social behaviour.

It’s not out yet, but according to The New York Observer, it should be available in time for SXSW.

“What we wanted to do is turn life into a video game. You should be rewarded for going out more times than your friends, and hanging out with new people and going to new restaurants and going to new bars–just experiencing things that you wouldn’t normally do.”

So, a video game that rewards being adventurous and outgoing in, you know, real life?

Kottke is calling it the new Dodgeball. One significant change I’m wondering about, will it work in Canada?

TED Talk by Blaise Aguera y Arcas

What you are about to watch is truly remarkable, and it just gets better as it goes.

Using photos of oft-snapped subjects (like Notre Dame) scraped from [Flickr], Photosynth (based on Seadragon technology) creates breathtaking multidimensional spaces with zoom and navigation features that outstrip all expectation. Its architect, Blaise Aguera y Arcas, shows it off in this standing-ovation demo.
