Let me tell you right from the start that this display wall was created especially for viewing of those immense gigapixel photos that you have probably heard about until now. Just in case you are curious about them, here is the largest photo of this kind taken until present day - it is one of the city of Paris. The video below is an introductory one for the 22-megapixel display wall on which the creators navigate through a 13.3 gigapixel picture of Tromso, Norway, taken by photographer Eirik Helland Urke.

The 22-megapixel display wall itself was developed by two graduate students who simply wanted to have a powerful and more enjoyable system of navigating through the gigapixel images. Their combined efforts resulted into their Display Wall project that has its own laboratory now at the Department of Computer Science in the University of Tromso.

In the Display Wall laboratory, there is this Display Wall created out of 28 projectors and driven by a display cluster. This display cluster uses about 28 nodes for the actual graphics and a few more nodes for other various tasks. The projectors are all capable of rendering an image at the 1,024 x 768 resolution, which totals at 7,168 x 3,072 resolution for the entire Display Wall, from tiling the images together.

The screen supports multitouch functions, which you will see in the demonstration video at the end of this article with the help of 16 cameras placed on the floor, in front of the wall. This enhances the user's experience with the display wall by a thousand times, as you do not even have to touch the wall.

If you watch the clip, which I strongly recommend, you will be able to see the 22-megapixel display wall zoom in and out in a gigapixel picture, with a simple snap of your fingers and perform all sorts of multitouch functions that you will not find on any other gadget right now. I don't want to spoil the surprise, which is why I am not giving any more details.

There will be a paper released soon by the two students currently developing this sweet Display Wall, which is when they will unveil more technical details about their project. After seeing the movie, try and imagine how browsing through that 26 gigapixel picture of Paris would be like on the Display Wall.
