Minecraft news » Tutorial: Building Instant Redstone Wire

Mumbo Jumbo is at it again, this time with a guide for desktop users! New (to desktop) is the Observer block, which checks adjacent blocks for updates, and sends signals based on those changes. As luck would have it, the check/update cycle is essentially instantaneous, allowing for instant, long-distance redstone signals, which might otherwise take a considerable amount of time to pass signals through numerous relays, block/torch combinations, and the like.

How might something like this change redstone computers, custom maps, or even just basic base modifications?
