What started as testing of what a piston can push led to roller coaster madness! After I got tired of spinning Agent around in a loop, I got a pig, a creeper, and a GIANT to take the ride as well. Sadly, the skeleton didn't make the cut, something was causing him to get stuck.
The important part of the contraption is the fact that the center rail is being manipulated by a piston. With the setup, it slopes in different directions with each state.
But yeah, just killing time here. :V Agent will be posting a video of the Giant's ride soon..
