One of the great features of Flickr is that you can subscribe to be notified via RSS whenever someone posts a photo tagged with a search term of your choosing. One of the tags I subscribe to is ‘Mosaic,’ which comes up with lots of photos of relic-variety mosaics, as well as the occasional mind blowingly awesome modern mosaic.

     Today’s feed contained this image. What is it? That requires a bit more explanation.

     There is a group on Flickr called ‘Longline‘ that is described as follows:

     “The idea of this group is to create a large mosaic of collective pictures, that has a web of lines running through all its constituent images, separating the full image into patches and creating emergent shapes. The concept should be visible in the group icon I created from the first four images in the pool. Join in the fun!”

     Really nerdy people will wonder if the production of this mosaic is automated, and I’m going to venture a guess that it is, based on the tagging methodology for the longline group:

     “The picture should be tagged with the “long line” tag. In addition there needs to be a “LL” tag coding the sides the line connects to in the picture. The sides are numbered, starting from the top in clockwise direction. A picture connecting the left to the bottom and right would thus be tagged with “LL234″

     …So it looks like the latter tag could easily be used to write an application to logically arrange the images into a connected mosaic, based on which sides are specified (Further research shows that I was right).

     The first thing I thought of when I saw the mosaic was the NES game Pipe Dream:

     In summary: Obscure puzzle game sub-genre + Flickr group + mosaic + this iPhoto poster tutorial [via Waxy] = some awesome wall-art.
