Not yet. But its like: I try to do something (redstone creation) , if its good, I'll build it it.
So far: 2 doors protected by a 10 lever combination lock, 1 door protected by a 4 button combination lock, a door where you have to press buttons multiple times to open it, a piston lift, etc. etc. Yeaaaah, not that much, but I like it so far.
Oh and who is interested in the flatland: I made it in MCEdit
