A photo-based game called Bickr has emerged around the photo sharing Flickr.

Bickr takes advantage of the community aspects of Flickr, by encouraging individuals to take pictures and enter them into a contest using Flickr's tagging system - you could have a contest around any tag, from "cats" to "winterwonderland." Tagging as a social phenomenon in action.

bickr uses flickr's tagging system as the basis to identify group affiliations, associate image(s) with game(s), and discover group commonalities and differences by tag(s).

bickr groups are those interested in finding commonalities and differences from within and between groups and establishing image based dialogue between different communities.

bickr will succeed because people love to take photos. More importantly, people love to share photos. bickr harnesses an individual's desire to share imagery to effect group interaction.

I think it's a great way to take advantage of Flickr's tagging and grouping systems. It's a seamless way to integrate into a widely disparate group based upon a common interest in the contest at hand. And it might be just that little push needed for some people to really get into Digital Photography or to start participating in online communities. Really interesting development.
