Are there any world wrap or wraparound plugins for Bukkit?

I am looking for plugin that does something similar to this:

 

You are probably right. You would have to use either a custom world generator or make a custom map yourself.

But as for generating chunks on the other side of the map directly in front of you, I think is possible.

The idea behind using region file borders is you could somehow copy the region file on the opposite side of the map in front of you. There would be far less code needed relatively speaking to copy region files compared to copying chunks within region files. Which is why I added a perlin noise in the background to represent the terrain. Notice it repeats once you walk on the edge, as well as the p2 and p4's view distance.

It doesn't matter so much that Minecraft terrain generation can't generate seamlessly. I can use a cusrtom built map or superflat for that, but the copying and translating of region files or chunks so you seamlessly teleport from one end of the map to the other when walking past the world's edge is what I am primarily interested in.
