The Flying Circus and the Super Happy Fun Slide are the best named ones.
The Time Travel Technology wonder is actually quite interesting and is not like any of the other wonders currently in existence, but it could be argued that it is too powerful to choose your events, and since events are random, it would be quite difficult to code. The Mind Control Device is also interesting, and doesn't suffer from the same problems.
The Shrink Ray is just too powerful. Doubling your citizens doubles your collections, so the wonder would have to be quite expensive. The High Heel Factory is just a weaker version of the Pentagon, so it's not really needed.
As for the community, I'd say it's evolved, but in a different direction. The players of this game shape its history and future, so if there is something that you do not like about the current climate, then I encourage you to branch out and forge your own piece of history.
