"Marketplace" was the theme of the World Wide Panorama's spring equinox event this year. 250 photographers from around the world participated: each contributed a 360 degree Quicktime Virtual Reality panorama, which can be rotated and explored on the internet. Cortes is on the map with its most unique marketplace: the Free Store at the Recycling Centre, photographed by Irene Blueth. See it here:
