The Minecraft Enterprise started out with this: (COMING SOON - BLOG NOT YET POSTED)
There was no raised bridge. The bridge was cluttered with gadgetry and redstone. The saucer was too thick.
I now call it the "First Enterprise" or the "Incorrect Enterprise".

The next version looked like this: (COMING SOON - BLOG NOT YET POSTED)
The bridge was raised. Unfortunately, this Enterprise, although it had been going so well, did not make it till the end. The world corrupted itself halfway through, and I had to start over.
I now call it the "Second Enterprise" or the "Corrupted Enterprise".

The present version looks like this: http://www.planetminecraft.com/project/uss-enterprise-ncc-1701-in-minecraft/ The exterior is complete. I didn't upload a picture simply because that link contains two.
I now call it the "Third Enterprise" or the "Completed Enterprise".

I was finally satisfied. Now, the First Enterprise probably would have sufficed had I not received critique on it. My collaborator on the Third Enterprise was the one who gave it. So I built the Second Enterprise. That probably would have been the final, had it not been corrupted. Because of that, I built the Third Enterprise, which is the one you see on Planet Minecraft today.
