Cool stuff from flickr

Searching for groups in flickr.com, I came across this one:

http://www.flickr.com/groups/infinite/

I wonder if there are more unusual groups.  If you see something else, post it here.

Woah, Flickr now has maps.  So you can geotag your photos:

flickr.com/photos/mig/227677458/

Click on “map” on the lower right, under additional information.
