TIS-3D is a Minecraft mod inspired by the brilliant game TIS-100 (go buy it if you don't own it yet). It takes the concept of minimal, programmable nodes and expands it to the third dimension, allowing you to build multiblock computers from different modules. Basic modules are the executable module, which can be programmed in very basic ASM (as introduced by TIS-100), and the redstone module, which allows reading and writing redstone signals, enabling basic interaction with the world. This mod is licensed under the MIT license. All assets are public domain, unless otherwise stated; all are free to be distributed as long as the license / source credits are kept. This means you can use this mod in any mod pack as you please. I'd be happy to hear about you using it, though, just out of curiosity.
