I'm pretty sure this was stolen. I've used this texture pack in 1.8 before.
I can tell you it was not stolen, it was an idea i came up with and made it one my own. HOWEVER, turns out many people have made different versions of this same type of thing.
This is a little creation i made that makes the most common blocks have a transparent hole in the center, unveiling many caves underground.

The level of non-legitimacy is somewhere between using the old F3 monster finder trick and X-ray mod. This can be very helpful!
