Oops... I guess I was a little too quick there...

What I meant was that you could use an alternative camera
that views 360 degrees. With some camera-types the rendered
image would then automatically be tiled some way or another.
If you want to tile a texture you can just put the texture
on a sphere and place the camera inside the sphere.

But as I said, I don't think that way gives satisfying
results...

Maybe you could use a regular pattern with a lot of warps?
This could probably give interesting results if used cleverly.

But, well, you asked for a superpatch solution,
I can't help with that right now.

Wild stuff, but not tileable. Thanks for showing anyway.
