A mod that takes ideas from the old Light Bridges and Doors mod and takes it even further, adding Halo-inspired, redstone-compatible technology.
Currently the mod adds hard light bridges and barriers, and long distance light energy emitter and receiver to send redstone signals far away, even underwater.
Placing and removing bridges, barriers, and lights in water does not replace or remove water, so using them underwater will not leave behind undesirable air blocks.
I have tested the Alpha version thoroughly and it is quite stable, I have it in Alpha because I still need to add content that I want to appear in the first final version.
