Microsoftie Jordan Schwartz reports that the "Pixie Hunt" test run in Pioneer Square went pretty well, except for a few kinks with uploading photos to Flickr and distributing those to other players. You can see some of his photos from the event here.
"Folks still had fun running around completing the tasks and taking pictures," Schwartz said in an e-mail. He's planning another test before debuting the game on June 12 at the Where 2.0 conference.
