SMP Combo Lock Gateway

Based on Sethbling's repeater lock design, this gate allows anyone with the code to enter, and has a switch to lock the place from even those who know the combo! Useful for cities, VIP areas, that kind of thing. Also included are some decorative turrets on the ceiling, and a door that allows access to some of the main circuitry, in case it bugs out. Also, If you watch Sethbling's video (Titled "Repeater Lock -- A Minecraft Tutorial"), he will show you how to reset or change the combination , using his original model. In case someone decides to lock you in, never fear! There are iron doors to get out as well!

Additional Notes

This design is very simple and can be made to be very compact, so feel free to use it, as long as you give Sethbling proper credit.
