Hamster wheel in Minecraft plus two old concepts

Usually, the content you see from me is not always the best of what I have to offer. I build many machines in my worlds, but I only share some of them with you.
So I thought, I worked hard on these two machines and I'm really proud of them, maybe I should upload them. I made them in 1.8, and it's quite shocking both still work perfectly in 1.9.
I also have another concept that isn't old.

Here are the concepts:
Hamster wheel: A working wooden hamster wheel that spins when you walk on it.
"Whoa Belly": Inspired by Rollercoaster Tycoon, this machine lifts you up into the air slowly, then drops you down very quickly.
Impossible chamber: You've probably seen impossible chambers before, but I made this one myself, in my own style. Inspired by the Code.

 

That's amazing! Very well done!

 

Looks very cool :P

 

Awesome!!! (You are kinda better than Sethbling XD)

 

This is one of SethBling's very old videos, it's called "My Greatest Invention Yet"...

Seth is 69% better than me.
