It's always interesting when you're made to re-evaluate and look at things differently. Cirque du Soleil has been doing that for years now; traditional 'circus' acts became fascinating entertainment that could make us stroke our chins or drop our jaws. In other words, something you thought you knew was presented in a new light. And yet the underpinnings of what Cirque does are not brand new - it did not invent the wheel or discover fire; instead, it took elements that existed already, and did something that no one had seen before. In other words it represents invention rather than discovery, but nonetheless it has created something compelling....not to mention the fact that it's generated a ton of revenue, spin-offs, and imitations.
