BARCELONA—Most pictures you find of Mobile World Congress (MWC) are likely to be the same thing: a picture of a smartphone or tablet tethered to a table. MWC is more than just a collection of smartphones on tables, though. It's always fun to point the camera at all the other things that happen at the big show to bring a bit of the MWC experience home. MWC is full of massive crowds and hundreds of vendors all competing for attention. The need to stand out leads to a crazy atmosphere, with interesting booth designs, LED light shows, sculptures. decorations, and all sorts of fun booth gimmicks.
