Appearing Corridor/Tunnel Bore -- Redstone with ChartreuseK
Channel: Chartreuse Kitsune
Date: 2013-12-31

Just a quick contraption inspired by Sethbling's flying carpet. After seeing that and his sleigh video I thought I'd see what I could come up with using stacked command block minecarts. I wanted to make something simple but practical and this is what I came up with. It's a wall that moves out at walking speed to reveal a hidden corridor. It could be used in a custom map where you want an objective to reveal a passage slowly and not just open a door. Or it could be used on a short path to make a hidden door in the wall that slides inward an open. Perhaps you can think of something else that could use it?
