Fujitsu Celsius equipment was used to stitch together thousands of individual photographic images to create large-scale 360-degree panoramic images: an 80-gigapixel image of London was published in November 2010, stating: “using this excellent workstation allowed this record-breaking photo to be created a few weeks faster than would have been possible on any other available PC.” The 320-gigapixel photomosaic of London published in February 2013 was prepared on a Celsius R920 in three months' time.
