I picked this up from gizmodo the other day - 3D Map jolly good fun. Not too sure about the absolute accuracy of the movements, mind.
If we can have A 244/R 246A, ODX 246A/R 246B, A 246B/ROD 1, OD 1/ROD 2 then I'm going to have A (7)88/R (7)90A, NHX (7)90A/R (7)90B, A (7)90B/RNH 1, NH 1/RNH 2 and hang the consequences!
