This is the Ars Electronica 2009 entry for xRez Studio. It is being shown in "Deep Space" aec.at/center_exhibitions_ds_en.php?id=96 a partial "CAVE" environment for large audiences.
The space is projected with 8 "stitched" stereo 2k projectors, resulting in an amazing amount of detail. The audience sits on the floor that is also a projection surface or they can view the work from a balcony.
Interactive zooming Gigapixel images make great content for a display like this. You can see the Deep space operator wearing the orange shirt, he is navigating the image via an iPhone interface. The installation will be part of a 2 year exhibit in the museum, aec.at/center_exhibitions_dsdetail_en.php?id=55 .
