While fooling around with texture ideas on a build, I accidentally lined up two barriers - The one I was working on (spruce leave texture) and one in the background with no texture..

This has got me wanting some kind of texture-inside-of-texture version of the barrier, or maybe the ability to switch to it with the hammer. Pictures included for reference.

I can toy around with the idea a bit.

Awesome! If it's possible (and simple enough) it would be cool to have on the other blocks, too.

An easy solution would to be able to apply leaf blocks to create this effect. I might limit the effect to just barrier posts, though.. unless you can think of another area this could be used.
