The PureView Club's Mark Wielaert was at MWC 2013 - but rather creatively he's chosen to show off some Nokia 808-shot photos of the city of Barcelona and of his trip there, rather than of the somewhat more boring show floor.

Note that some of the (very different) photos in this 8-shot gallery were shot in full 33 megapixel resolution and that full resolution versions of all the photos here are available via Flickr.
