Whilst learning about lua and minetest's api I created a basic ender chest mechanic. I do not wish to further this mod but you can and I don't care what you do to it.
Things that could be added ender chests from feed the beast where the player can input 3 dye and it would connect to all the chests of the same combination.
Things that should be added are new textures, it uses the default chest for now.
I don't think these save the inventory upon world exit :( but the mod was thrown together in 5 minutes.
Crafting recipe is 4 obsidian in the corners, a chest in the middle and the rest are diamonds.

Even though I said I don't care what happens to this mod, I'd still like a little recognition, just a "based on super_tnt's ender chest" on your topic would be nice.
