There's also supposed to be something special in the Swiss display ...
Given the aerospace theme of the Swiss show, and following an episode of Pyros, I immediately think about a flying device with some sort of fireworks (i.e.: gerbs) attached to. From a competition in South Korea, Pyros featured some shooting of a bird-shape flying thing which came into life with some gerbs. That would potentially be a winning ingredient for the competition.
With a such perspective, I also bring to your attention a prototype currently tested by Disney, presumably for the new Avatar-theme land to be built in Animal Kingdom. It is an ultralight dragon-shape mechanical aircraft:

I suppose that such flying devices may appear more often in the future in various entertainment shows.
