Months ago, right after I started using BTW I discovered the wondrous world of Youtube and it's many Minecraft contraptions. One such contraption was a 3x3 block door that opened at the press of a button. The maker stated with absolute certainty that getting it to close would be nearly impossible. I decided to build a door that would open and close at my whim!
Instead, I have an almost horridly complex door mechanism that has 4 buttons(As opposed to the one of the original), practically requires a combination and is harder to open than close. But it's mine. And that makes it all worth it.

There you have it. I realize that the screenshots aren't very good, but it's a door. It'd be easier to show off with video, but I don't have a video program, nor a video editor. If you ever need a combination lock door, you can use this one freely.
If you have any questions, feel free to ask. I'm not afraid to tear the edifice out to show off the inner workings if someone want to see them.
If you have suggestion on how to make my wiring more efficient(Or, even better, make it all one button), or where I might find a good video recording program, please share!
