Has to be seen to be enjoyed. Pretty cool stuff. Big fan of kinetic art and Rube Goldberg machines. Though this isn't an RG, it still wins the kudos award from me.

wow! that's pretty amazing!

I couldn't even begin to imagine how someone could build something like that. That's amazing.

blows your mind just to think how this master piece was put together and the hours he/she spent getting it to work

I'm really fascinated by stuff like this. Have to wonder about the minds that designed it and the amount of math and etc that goes into creating it to run perfectly like that

Hot Wheels on steroids

wow, to figure that out must give them a headache.
