I'm totally new to textures for Minetest but out of boredom I started editing the textures in my Minetest. I've replaced a number of them with "real" textures. If I continue there may be a complete texture set using "real" textures. Screenshots below. However is there an interest for such a texture pack?

These are by no way the finished thing. This is a couple hours of boredom. Other textures were modded as well such as the steel sword and steel axe as well as the brick block and single clay brick. Jungle grass was also edited as well as grass (but the grass didn't turn out too well). Also edited the player graphic for my own use and edited the wood planks graphic.
