a mod that is a 2x1x2 block resembling a tardis centre console that when hit asks for coordinates (disregard up or down) then generates a 1x2x1 portal at the coordinates (above ground{by setting the y axis to 100 then dropping} to reduce hazard) this is a mid 1930's police-box (tardis) links that to a archway (wired through to console so multi tardis possibility) when the user sends a new set of coordinates the old portal (exterior tardis) is erased (at default the tardis faces north i confronted by a wall it rotates if all sides are blocked it refuses to materialize)
