PROLOGUE:I have a very large design that I need a good concept for. Let me first paint a picture in your head.I am going to be building an underground city. It isn't just any underground city though. This underground city is going to be under an ocean. The roof of the underground city will be the ocean itself. This isn't a small underground city either. It's roughly 200x200 so... well I'm going to be working on it for a WHILE. Not to mention all the other things that are going along with it.TASK:So what I need help with is the roof of the underground city. It will be stained glass but I am not certain what I want it to look like. In my head I imagine an intricate, perhaps Fibonacci sequence that will span the entire roof/floor of the ocean. Of course many people immediately jump to pixel art but pixel art would be a little difficult to make out with a blue background and being some 40-50 blocks above your head. I think a design would do it much more justice. The ideas floating around in my head never stop but I thought I could make this a little more fun and turn it into a giveaway. PRIZE: For the design I end up going with I will be supplying said person with some unique prizes. Just to make everyone happy I am going to be offering 200k rupees. I will also supply the winner with a tour of the progress in getting this project under way already and will of course keep them up to date. My personal favorite prize: access to one of the most efficient guardian farms in all of emc. This farm was made painstakingly and will be the centerpiece of the underground city. This city/farm/project is located in an undisclosed location at a private outpost. I have been working on this whole thing for a good while now and have some pretty cool stuff going on out there.If the winner is not the only design that amazes and awes then I will definitely hand out consolation prizes generously. Nothing set in stone though.Tl;dr I need a ceiling for my underground city which will also be the floor to a 200x200 ish ocean. I want a design(pixel art will be considered but discriminated against) to do the ceiling/floor in stained glass. As of yet I do not have a contest end date. I will gauge it on entries. If you have an entry but are working on it let me know so I don't close the contest early.Additional Information:Templates/pictures/drawings and/or general design ideas will be considered. Please PM me with "Large build design" as the subject with entries. If you have any queries please post it here on this thread so that I may answer it publicly and not have to continue to answer the same questions over and over.
