My first works: http://www.youtube.com/watch?v=8W1266n_kn0&feature=plcp&context=C3539748UDOEgsToPDskI-6GUCw5x8uG0Aqdqn_YU- http://www.youtube.com/watch?v=Tfn5dqyICME&feature=plcp&context=C30fa57aUDOEgsToPDskL5f-bups1677deGYzMCZtC My latest work: This is a building which has an entrance hidden by a waterfall, and requires 2 obelisks to be powered by redstone torches in order for the doorway to open up with a large F in front: http://i41.tinypic.com/315zlg1.png http://i42.tinypic.com/21x008.png it also uncovers a stairway instead of stone bricks, being replaced by pistons pushing from the sides. Also, when going inside, you'll quickly notice a button near the exit, this button allows you to retract the obelisk torch placeholders so you can remove the torches without going outside and thus, closing the door again allowing the waterfall to flow back. http://i42.tinypic.com/29c877p.png Once inside and the door is closed, it doesn't mean you are stuck in there, simply wait a moment until you hear a "click" which means the lock is removed and the delay is ready to be inserted to override the obelisk's door opening system. by pressuing the button, a piston is pushing a block near the obelisks allowing charged delay's for about 40 seconds long to be injected into the same input that the obelisks give, once that delay is done, it runs back to another piston that pushes the block back to it's original position so it can't inject power anymore to the obelisk injection: http://i39.tinypic.com/8yfec7.png. The door system itself is pretty simple, first the waterfall closes or opens, on closing, the logo and door system waits for about 14 seconds in delay before opening, and pushes a piston forward for direct closing *leading power around delays* and retracting another one for un-necessary wanted opening. While it's closing, there's a piston making sure that during that time, the door cannot be opened again for sometime for no water splashing everywhere, basically, this system cannot mess up. There's security and fail-safe to it.
