In my theme park I got bored and decided to build a funhouse that has multiple layers and scenes in it, each with their own style and concept in mind to keep it interesting.. There's a bit of redstone work scattered about, along with command blocks.
 
If you'd like to see the Fun House for yourself, I have built it on mc.noobadventures.beastnode.net
Just type in /warp moosh
And the Fun House is towards the back of the park, so just keep walking straight out of the entrance.
