Club Float looks pretty, but ten other clubs in NYC are using that decor as well, and they draw a really boring yuppie crowd for the most part. The decor is just a backdrop, nothing really interesting or experimental going on there. A huge new club opened in DC (2K9) with a millenial/cyber decor, and it's the same thing.
When I go to a club, I'm more interested in the people, are they experimenting? Are they creating an intense scene that changes from week to week as the people change their interests? To me, that creates a moving art scene, one that is temporary but very intense, and a new performance every night.
