This game has great dynamic lighting capabilities, so why not put that potential to further use? It would be nice to have a block that emits light, but rather than a block that emits light in all directions, have a block that emits light in one direction only (albeit in a cone or arc or line of light). This “directional light block” could be directed by the builder, and in the end, many cool new lighting effects could be created which would also differ remarkably from the all-directional light sources. Seems to me that it would be worth the effort to make considering the reward would be more fantastical environmental atmosphere.
