Tiny little mod as a request from a friend who wanted a block that acted like Thaumcraft's Portable Hole when right clicked. That is, the blocks became non-solid and could be walked through.
Several different types of phasing blocks.
Regular phase stone and phase glass both become non-solid when right-clicked. Transition phase stone propagates the right-click action between phase stone and phase glass. Red phase stone is triggered when it receives a redstone signal. Trapped phase stone activates when a player or mob walks over it or lands on it when falling.
Phase stone is useful for creating player-only doors (as mobs are not able to path through it or activate it).
Feel free!
