In SMP om vanilla server.
Credits go to TheBigCactus for coming up with the design.
Yes, my portal is a bit smaller, but that's because the original desing isn't possible since it uses 26x26 portal, so I had to adjust. Also I miscalculated the columns’ size, so they are a bit smaller too. But it still looks epic. I'll add chains (or maybe I'll come up with something else) later. Or not.
